...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS SOUTHERN

NEW ENGLAND INTO THE MID-ATLANTIC AND OVER THE SOUTHERN HIGH PLAINS

INTO SOUTHWEST TEXAS...



...SUMMARY...

Scattered thunderstorm activity across the Mid-Atlantic region

Wednesday may pose a risk for severe wind and hail. Large hail will

be possible with isolated to widely scattered thunderstorms

developing over the southern High Plains into southwest Texas.



...Synopsis...

A trough will continue to lift northward into Canada D2/Wednesday,

with a cold front extending from the Northeast southward across the

southern Ohio Valley into the lower Mississippi Valley and westward

into southwestern Texas and eastern New Mexico. Scattered strong to

severe storms are expected near the front in the mid Atlantic and

near the high terrain of western Texas.



...Mid-Atlantic...

Scattered showers and storms are expected along the cold front

Wednesday afternoon across portions of the Mid-Atlantic. The

downstream air mass will include a narrow plume of weak to moderate

instability. Though deep layer shear and mid-level lapse rates will

be marginal, steep low level lapse rates will support a few

instances of strong to severe winds.



...Southwest Texas and eastern New Mexico...

Isolated to widely scattered thunderstorms are expected to develop

near the high terrain within the upslope flow regime across western

Texas and eastern New Mexico Wednesday afternoon. Forecast soundings

depict sufficient deep layer shear to support supercells. Moderate

to strong instability and steep low to mid-level lapse rates will

support potential for large hail and a few occurrences of severe

winds.
