severe weather threat across the Southeast and upper Ohio Valley...

Lakes Thursday night into Friday morning and ...



A low pressure system is currently consolidating over southern

Texas as a dynamic upper-level trough is getting ready to move off

northern Mexico and then vigorously interact with moisture

returning from the Gulf of Mexico.  The clusters of strong to

severe thunderstorms that have already formed and impacted the

western Gulf states are just a precursor of what the system may

produce later today when it is forecast to intensify rapidly with

thunderstorms erupting over the Arklatex region.  These

thunderstorms are expected to contain very heavy rain, hail, high

winds, and the possibility of tornadoes across the interior South

through tonight as a potent cold front is forecast to sweep across

from west to east.  The low pressure system itself is forecast to

intensify, expand and track toward the northeast for the next

couple of days, with moderate to heavy rainfall engulfing much of

the eastern U.S. by Thursday.  The heaviest rainfall is expected

to impact the central to eastern Gulf coast region today through

Thursday morning, with another heavy rain axis from the Arklatex

region to the Midwest following the center of the intensifying low

pressure system.  The low pressure system is forecast to intensify

and expand further Thursday night into Friday morning, bringing

high winds into much of the eastern U.S. as well as the Great

Lakes, Midwest and the Ohio Valley.  Thunderstorms should exit the

Southeast by Friday morning as the cold front moves off the coast.

 However, the Mid-Atlantic and virtually the entire Northeast will

likely be engulfed by moderate to heavy rain along with high winds

especially just ahead of the potent cold front trailing south from

the center of the intense and expanding low pressure system.



Outside of the intensifying low pressure system, relatively quiet

weather is expected for the next couple of days with a stable

upper ridging building into the western U.S.  Scattered rain and

snow showers are expected to fall across the northern Rockies and

northern High Plains today before reaching into the northern

Plains as a clipper system swings across these areas.  Light

precipitation is forecast to reach the Pacific Northwest Thursday

night with the arrival of the next Pacific system.  Otherwise,

improvement in the fire weather threat is expected across the

southern High Plains where elevated fire danger is confined to the

Texas Big Bend today, followed by portions of the central Plains

on Thursday.
