...Heavy rains will raise a risk of flash flooding across much of
Oklahoma on Wednesday...

...Unusually cool weather will continue to dominate the eastern
half of the Nation...

Heavy rains and thunderstorms that impacted the front range of the
Colorado Rockies on Tuesday will shift southeastward across
Oklahoma on Wednesday.  The most organized area of precipitation
should develop to the northeast of a surface wave slowly dropping
from southeast Colorado to north central Texas...and an abundance
of moisture in place could lead to rounds of heavy downpours and
flash flooding.  The threat for flash flooding should diminish on
Thursday as the wave weakens while tracking farther southeastward
through Texas...but moderate to heavy rains...with embedded
thunderstorms...will still be possible over portions of East Texas
and the Lower Mississippi Valley.

An anomalous trough carved out over the eastern half of the Nation
will keep temperatures below normal from the Great Plains to the
Atlantic Coast.  Conditions will be especially cool across the
Great Lakes and interior New England...where weak disturbances
moving through aloft will bring cloud cover and the chance for
showers and thunderstorms.

Summer heat will persist across northern portions of the
Intermountain West and Rockies Wednesday and Thursday...beneath an
upper ridge amplified over the Western U.S..  Farther
south...monsoonal moisture fueling scattered showers and
thunderstorms across the Great Basin and Southern/Central Rockies
should suppress daytime maximum temperatures.
