Like a broken record, today will yet again feature chances for severe weather and flash flooding across the central and southern High Plains. Thunderstorms are expected to develop over eastern New Mexico this afternoon and slowly push eastward into West Texas by this evening. A few storms will be capable of producing large hail, damaging wind gusts, and isolated tornadoes. Additionally, flash flooding will also remain a possibility where ongoing heavy rain is currently falling across southwest Kansas, as well as the southern High Plains thanks to the slow moving nature of the thunderstorms. By Monday, a cold front located over the region will push southward and shift the threat of severe thunderstorms to southwest Texas and far southeast New Mexico. The Big Bend in particular will have the greatest risk of destructive hail and tornadoes. SPC has issued an Enhanced Risk of severe thunderstorms for this section of Texas on Memorial Day. Showers and thunderstorms capable of intense downpours will be found elsewhere across the southern Plains to end the month of May, with maximum rainfall amounts over 3 inches possible. WPC has issued a Slight Risk of Excessive Rainfall on Monday that extends from south-central Oklahoma to north-central Texas. Another day of cool, damp, and dreary weather is in store for the Mid-Atlantic and Northeast today as a coastal low pressure system begins to develop. Light to moderate rain is forecast to fall from the Delmarva Peninsula to Maine, with the highest rainfall amounts located throughout New England. Gusty northeast winds and chilly temperatures will also accompany the system, with Coastal Flood Warnings and Advisories extending from the Chesapeake Bay to Massachusetts. In case that wasn't enough to ruin outdoor activities or a day at the beach, temperatures 20 to 30 degrees below average remain locked over the region. Highs are forecast to only reach the upper-50s as far south as Virginia, which is expected to lead to plethora of daily records. Fortunately, the aforementioned low pressure system should begin to exit the Northeast on Memorial Day and lead to increasingly pleasant weather as we head into the beginning of June. Meanwhile, a building upper-level ridge over the western U.S. will likely lead to the hottest temperatures felt so far this year throughout the West. Excessive Heat Warnings and Heat Advisories have been issued for northern and central California, where triple digit high temperatures are forecast today and Monday. This is also likely to exacerbate the growing extreme and exceptional drought conditions found throughout the region. Snell Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
