A persistent weather pattern setting up across the mid-section of the
country will allow rounds of heavy rain and embedded severe thunderstorms
to repeatedly develop and travel eastward through the central Plains.  A
couple of slow-moving fronts will help focus these storms as they travel
eastward.  The southern front will help direct a general storm track from
the central High Plains through Oklahoma tonight into Tuesday.  The
northern front is forecast to bring a second episode of storm from
northern High Plains southeastward into the central Plains later on
Tuesday, and then toward the mid-Mississippi Valley and the Ozarks into
Wednesday.  Some of the heavy rain and thunderstorms will likely lead to
flooding issues along with frequent lightning, possible high wind gusts,
large hail, and a few tornadoes.  Farther to the north and east, showers
and thunderstorms are expected to move across the Midwest and the Great
Lakes at a steady pace through tonight near and ahead of a cold front. 
While some of these activities will likely be heavy, the steady eastward
motion of the front will keep the threat of flash flooding at bay for
these areas.  By Tuesday, the showers and thunderstorms are expected to
reach the Northeast, Appalachians, across the Tennessee Valley and the
Mid-Atlantic as a frontal low pressure wave intensifies and moves into
southeastern Canada.  By later on Wednesday, the rain is forecast to begin
exiting new England as the showers and thunderstorms from the mid-section
of the country move into the Ohio and Tennessee Valleys, southern
Appalachians, and the interior Southeast.

Elsewhere, a weakening Pacific system will bring a period of unsettled
weather through the northern Rockies followed by the northern Plains
through the next couple of days, which would include some high-elevation
snow near mountain peaks.

Meanwhile, temperatures are forecast to continue soaring well into the
100s over central Texas for the next couple of days where daily record
high temperatures will be challenged.  Meanwhile, near normal temperatures
along the East Coast will slowly yield to increasing heat and humidity and
increasing chance of thunderstorms by Wednesday.

Dry and above normal temperatures are forecast for the Southwest.  In
contrast, a period of rain is forecast to reach the Pacific Northwest
Tuesday night before tapering off during the day on Wednesday.
