...Stormy weekend forecast across the Great Lakes/Ohio Valley and much of
the East Coast with some severe weather and flash flooding possible...

...Risk of flash flooding returns to the Southern Plains this weekend
including portions of hard-hit northern/central Texas...

..Heat builds over much of the eastern and western U.S. this weekend with
heat-related advisories and warnings in place...

A Summertime airmass rich with moisture ahead of a cold front progressing
from the Midwest/Plains into the Northeast will fuel widespread
thunderstorms across much of the eastern and central U.S. this weekend.
Storms are expected along both the front over the Lower Great Lakes/Ohio
Valley and well ahead of the front along the East Coast Saturday. An
upper-level shortwave supporting greater shear along the cold front from
the Lower Great Lakes into the Ohio Valley will bring the threat for some
severe weather. The Storm Prediction Center has issued a Slight Risk
(level 2/5) mainly for the threat of damaging winds. In addition, the
plentiful moisture will lead to locally heavy downpours and the risk for
isolated flash flooding both here as well as across portions of the
Carolinas/Mid-Atlantic northward into Upstate New York/western New
England. The cold front will move eastward into the Northeast on Sunday
helping to focus storm coverage across portions of the Mid-Atlantic
northward into the northern Appalachians and Upstate New York. The threat
for training/repeated rounds of storms on top of the anomalously moist air
mass has led to a Slight Risk of Excessive Rainfall (level 2/4) with
scattered instances of flash flooding possible. More isolated instances of
flash flooding can be expected westward along the stalling front through
the Ohio Valley.

To the southwest, the cold front is expected to stall across the Southern
Plains with a position likely dictated/reinforced by ongoing convection.
Plentiful Gulf moisture remains throughout the region and the passage of
an upper-level wave will help to support widespread storm development both
Saturday and Sunday. On Saturday, the greatest threat of storm coverage as
well as heavy rain rates/totals stretches from Oklahoma southwest through
portions of northern and central Texas, where a Slight Risk of Excessive
Rainfall is in effect. The expected heavy rainfall totals along with
already sensitive, wet antecedent conditions may lead to scattered to
potentially numerous instances of flash flooding. The Slight Risk extends
into western Texas and eastern New Mexico due to the threat for heavy
downpours and scattered flash flooding here as well. The front will make
little progress into Sunday, again likely dictated by convection
Saturday/Saturday night, with a similar threat for more heavy rainfall
overlapping most of the same region as Saturday. A Slight Risk remains in
effect for more scattered to potentially numerous instances of flash
flooding, especially for areas that are impacted Saturday.

Hot temperatures are in store this weekend across much of the eastern and
western U.S. In the West, most locations will be in the 90s to low 100s,
with low 110s in the Desert Southwest, as an upper-level ridge builds
overhead. The most hazardous heat is expected across the central
California Valleys into the interior Pacific Northwest/western Great
Basin, with areas of Major Heat Risk expected (level 3/4), indicating a
level of heat dangerous to anyone without access to adequate air
conditioning or hydration. Much of the region is under heat-related
warnings and advisories. Highs into the 90s and very muggy conditions will
also lead to an uncomfortable weekend in the East, with areas of Major
Heat Risk expected across the Interior Northeast/Lower Great Lakes
Saturday, and expanding in coverage across much of the Southeast/Carolinas
Sunday. A cold front passage will bring a little relief to the Interior
Northeast/Lower Great Lakes on Sunday. Onshore flow will keep temperatures
much cooler in coastal New England. Areas of the Plains and Midwest will
see below average temperatures and more temperate Summer conditions with
the cold front passage and areas of widespread clouds/precipitation. Highs
on Saturday will be in the low to mid 80s for most of the northern/central
Plains and Midwest, with low 90s into Texas. Warmer conditions will return
to more northern locations by Sunday as highs warm up into the mid-80s to
low 90s, while much of the central/southern Plains and Texas will remain
in the 80s.

...Much of Florida could see heavy rain next week...


...Overview...

A typical summertime pattern will be in place much of the medium
range period next week with an expansive upper ridge stretched
across the Southern U.S. and progressive shallow troughs moving
through the northern stream flow. A shortwave from the base of an
initially zonal jet across Canada will amplify over the northern
Rockies by Tuesday, drifting east through the northern Plains and
Great Lakes into next weekend. This trough will send a cold front
through the northern and central U.S. aiding convection over much
of the country from the Rockies and eastward. Elsewhere, weak low
pressure near/over Florida will keep daily rain threats over the
Sunshine State through the week, while monsoonal moisture increases
throughout the week in the Four Corners states to south-central
High Plains. Heat in the West early to midweek should lessen by
later next week, while warmer than average temperatures affect the
Ohio Valley to Northeast Tuesday onward.


...Guidance/Predictability Assessment...

The guidance tonight continues to struggle with the details and
timing of shortwaves trough the northern stream flow, but overall
show agreement on the larger scale pattern evolution next week. The
ECMWF was on the faster side with the main shortwave through the
northern Plains/Great Lakes, with the GFS slower. This should
progress across the Great Lakes next Friday with uncertainty on
additional reinforcing energy into the overall trough. A closed
upper low in the Gulf of Alaska early in the week will round a
strong ridge over the Northeast Pacific and drop southward towards
British Columbia and the Pacific Northwest. The evolution of this
gets somewhat murky by later in the week with the GFS more open and
much faster with this than the ECMWF and CMC which maintain closed
lows. The ensemble means are very weak and broad with this
feature, indicative of a lot of spread in various ensemble members
as well.

The WPC forecast tonight used a blend of the GFS, ECMWF, and CMC
early in the period, transitioning to majority ensemble mean
guidance by late period. Maintained some modest contributions from
the deterministic guidance though just for a little extra system
definition. Maintained relatively good agreement with the previous
WPC forecast as well.


...Weather/Hazards Highlights...

Much of the nation east of the Rockies will be active with typical
summertime convection in a warm and unstable airmass. First, a
lingering front across the East will maintain convective threats
across the Southeast. Just south, a weak surface trough/low will
retrograde across the Florida panhandle with enhanced moisture and
forcing to fuel a heavy rain threat. Models remain all over the
place in terms of amounts both across the Southeast and Florida, so
holding with nothing more than broad marginal risks right now for
both Day 4/Tuesday and Day 5/Wednesday Excessive Rainfall Outlooks
across the Southeast and Florida. Rainfall may shift westward with
time more towards the Gulf Coast later in the week.

Farther north, a cold front moving through the northern/central
Plains and eastward next week will support showers and
thunderstorms with ample moisture and instability, resulting in a
heavy to excessive rainfall threat. Both EROs on Tuesday and
Wednesday feature broad marginal risk areas from the northern High
Plains eastward into the Upper Midwest and southward towards the
Middle Mississippi Valley/Ohio Valley. These are intentionally
broader than they need to be just given the uncertainty in the
guidance on where convective maximas are, and it is possible that
smaller embedded slight risks may be needed if the guidance comes
into better agreement.

Elsewhere, monsoonal moisture will gradually increase in coverage
across the Southwest/Four Corners/southern Rockies region. For
Tuesday, continued a marginal risk in far western Texas and the
Sacramento Mountains (particularly over very sensitive burn scars),
with the marginal risk expanding westward into southeast Arizona
by Wednesday. More widespread monsoonal moisture will make its way
northward in this region later in the week.

Hot weather across the West should start to moderate by the start
of the period with temperatures below normal farther east into the
northern Plains with high temperatures 15 to 25 degrees below
normal for Tuesday and Wednesday. Temperatures look to be a few
degrees cooler than average for the south-central U.S. for much of
next week as clouds and rain hold temperatures down. The Great
Lakes and Northeast will see a return to above normal temperatures
on Tuesday after the trough clears, with somewhat widespread Major
(level 3/4) HeatRisk showing up in those areas by midweek.
Meanwhile the Southeast should be near normal to a few degrees
above, for typical summer heat and humidity.

Surface high pressure north of the state will drift more
northward this weekend. This should allow for trade winds to
weaken into early next week, with some strengthening again mid to
late week as the high pressure starts to build back westward
north of the state. Clouds and showers through the next week will
generally favor the typical windward locations.

...THERE IS A SLIGHT RISK OF EXCESSIVE RAINFALL FOR MUCH OF THE
SOUTHERN PLAINS AND FOR PORTIONS OF NEW MEXICO...

A digging shortwave trough slowly moving across the Texas and
Oklahoma Panhandles and into Oklahoma tonight will act as a focus
for thunderstorms, as ample Gulf moisture streaming north across
the Southern Plains provides plentiful support for thunderstorms.
Much of the high resolution guidance suggests there will be 2
separate primary areas of thunderstorms today through tonight: One
will be along the TX/OK border, and a second one will be near or
over the Concho Valley, with a relative minimum of activity in
between. While this is the broader consensus, there is little
agreement on how those storms will evolve, including which areas
will be hardest hit with the heaviest rain. Given the sensitivity
for heavy rain in the Concho Valley especially, these prevalent
uncertainties support keeping the region in a very high end Slight
Risk for now. Since the bulk of the activity is expected tonight,
there remains at least one or two more forecast cycles before the
flooding rains get going over a broader area, so a Moderate Risk
upgrade remains quite possible with better agreement in the
guidance with future forecast cycles.

Neighborhood probabilities in the HREF guidance peak above 80% for
3 inches or more in a 40 km radius in much of the Slight Risk area
in Texas and Oklahoma. This lends credence to the high likelihood
that there will be flash flooding, but its magnitude and coverage
remains very low confidence.

Further west into New Mexico, the Slight Risk remains in effect
there to account for the sensitivities of communities in the
Sacramento Mountains north to the Sangre de Cristos. There is more
uncertainty here how any leeside storms will evolve, so here too
close attention will be needed for any potential targeted upgrades.

...THERE IS A SLIGHT RISK OF EXCESSIVE RAINFALL FOR PORTIONS OF THE
SOUTHERN PLAINS AS WELL AS FOR PORTIONS OF THE MID-ATLANTIC...

...Southern Plains...

The upper level shortwave responsible for forcing the thunderstorms
from Saturday night will cut off from the primary flow with the jet
on Sunday, This upper level shortwave will coincide with a
stationary front over Northwest Texas and Oklahoma. There will be a
continuous southerly flow of plentiful Gulf moisture across Texas
and Oklahoma on Sunday, but with limited forcing, the overall
coverage of showers and thunderstorms will be lesser on Sunday as
compared with D1/Saturday. The tradeoff in some areas with this
setup is because both the stationary front and upper level cutoff
disturbance will be very slow-moving, if moving at all, some of the
same areas that will likely see heavy rain from thunderstorms for
the second consecutive day. This is most likely in north-central
Texas and southeastern Oklahoma. For this reason, a higher end
Slight is in effect for this area. While storm coverage will be
lesser, due to the abundant moisture available for any storms, the
stronger storms will be capable of 2+ inch/hour rainfall rates,
which over sensitive areas will be plenty heavy enough to cause
localized flash flooding. Should the rainfall in this area
overperform on D1/Saturday, with better agreement in the high
resolution guidance, then it's possible a Moderate Risk upgrade may
eventually be needed. The chances of an upgrade are lower during
this period as compared with D1/Saturday.

...Mid-Atlantic...

Very few changes were needed to the Slight Risk that covers much of
the central Appalachians from Virginia north through upstate New
York. Abundant Gulf and Atlantic moisture will stream north up the
East Coast through the period, increasing PWATs locally to over 2
inches. A potent cold front will cross out of the Midwest and into
Pennsylvania and New York Sunday night. This forcing will result in
numerous showers and thunderstorms capable of very heavy rainfall
in the Slight Risk area. The greatest rainfall totals are likely
from northern Pennsylvania through central New York. Further south
towards the DMV, while forcing will be lesser, any storms that
form will be capable of heavy rainfall with abundant moisture
available.

...THERE IS A SLIGHT RISK OF EXCESSIVE RAINFALL FOR MUCH OF THE
CENTRAL AND SOUTHERN FLORIDA PENINSULA...

A westward-moving tropical wave will move across the Florida
Peninsula on Monday, with the greatest rainfall and threat for
storms expected during peak heating Monday afternoon. PWATs with
the wave will be over 2.25 inches in south Florida. While there
remains considerable uncertainty as to convective evolution and
placement, the sheer volume of moisture available for any storms to
draw upon in the formation of heavy rain will be more than capable
of supporting heavy rain and resultant flash flooding. Much of
Florida has been dry for soil moisture and recent lack of rainfall,
so the drier than normal conditions will likely mitigate any
potential flash flooding. Urban areas such as the Miami-Ft
Lauderdale metro as well as Tampa and Orlando will be at a higher
risk for flash flooding due to the slow-moving storms, which will
likely interact via cold pools through the afternoon. The Slight
Risk upgrade was coordinated with TBW/Tampa, FL, MLB/Melbourne, FL,
and MIA/Miami, FL forecast offices.
