Continue reading for today's outlook from the National Weather Service's Storm Prediction Center. -------------------- National Severe Storm Outlook THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE NORTHEAST/APPALACHIANS/MID-ATLANTIC STATES SUMMARY Scattered severe thunderstorms capable of damaging wind gusts and some hail are expected across the Upper Ohio River Valley and Northeast/Mid-Atlantic States during the afternoon and evening. Upper Ohio Valley to New England A shortwave trough will steadily amplify over the Great Lakes with a moderately strong belt of southwesterly mid-level flow across the region. Near/ahead of the eastward-moving cold front, increasing thunderstorm development is expected into the afternoon, increasing in both coverage and intensity. Ample mid-level height falls and around 40 kt of front-parallel effective shear could support a few initial/semi-discrete supercells prior to more prevalent upscale-growing linear modes, with the primary concern being damaging wind gusts. A brief tornado and/or hail could also occur given the relative strength of the wind profiles. Mid-Atlantic to southern Appalachians/Carolinas Widely scattered thunderstorms are expected ahead of the cold front during the afternoon, generally focusing on a pre-frontal trough as well as high terrain/Blue Ridge vicinity, with some additional sea breeze augmentations across the Carolinas/coastal plain. From roughly southern/eastern Virginia southward, upper 60s to lower 70s F dewpoints and diurnally steepening low-level lapse rates will yield a corridor of strong surface-based buoyancy ahead of storm development. Despite weaker deep-layer shear and limited midlevel height falls with southward extent, the strongly unstable air mass will favor eastward-moving thunderstorm clusters capable of producing damaging wind gusts. Somewhat stronger mid-level westerlies will reside over the Mid-Atlantic region, contributing to 30-40 kt of effective shear amid moderate surface-based buoyancy. This environment will support several organized clusters capable of scattered damaging wind gusts, and some locally higher concentrations of wind damage will be possible with any longer-lived clusters that evolve. Southern High Plains Along the tail-end of a composite cold front/outflow boundary extending westward into the southern Rockies/High Plains, widely scattered thunderstorms will spread southeastward during the afternoon. Given moist easterly low-level flow and 30-40 kt of effective shear along the boundary, a couple loosely organized storms will pose a risk of locally severe gusts and hail across parts of eastern New Mexico and far west Texas. Additional storms are expected along the boundary extending eastward across northern/central Texas to the ArkLaTex, though weaker deep-layer shear should limit storm longevity/organization.

Pollen Index: 10.1 Pollen Level: high Predominant Pollen: Grass, Oak and Birch. The amount of pollen in the air for Monday will be falling in the moderate range. This change results in part from falling temperatures, rising humidity, and heavy rains in the morning and evening which tend to wash pollen out of the air. With this amount of reduction in pollen levels, tomorrow should be better for allergy sufferers.
