A RELATIVELY STAGNANT UPPER PATTERN WITH TROUGHING ALONG THE
COASTS AND RIDGING OVER THE CENTRAL U.S. WILL PERSIST THROUGH THE
END OF THE WEEK, WITH COOL AND RAINY WEATHER FORECAST FROM THE
OHIO VALLEY TO THE NORTHEAST/MID-ATLANTIC. ALONG THE TRAILING END
OF THE FRONT, ISOLATED TO SCATTERED SEVERE STORMS (SOME OF WHICH
COULD PRODUCE INTENSE HAIL AND WIND) AND HEAVY RAINFALL REMAIN
POSSIBLE IN THE SOUTHERN PLAINS TODAY. LOOKING AHEAD THROUGH THE
FIRST HALF OF MEMORIAL DAY WEEKEND (SATURDAY EVENING), THE THREAT
OF SCATTERED SEVERE AND EXCESSIVE RAINFALL IS EXPECTED TO FOCUS
ACROSS THIS PORTION OF THE FRONT AS IT SLOWLY LIFTS INTO THE
OZARKS AND CENTRAL HIGH PLAINS WHILE A DRYLINE SHARPENS.
STORMS ASIDE, THE AFOREMENTIONED UPPER-TROUGHING OVER GREAT LAKES
AND NORTHEAST WILL FACILITATE COOLER TEMPERATURES ACROSS THE
NORTHERN PLAINS, MIDWEST, NORTHEAST AND MID-ATLANTIC THROUGH
SATURDAY. HIGH TEMPERATURES IN THE 40S, 50S AND LOW 60S WILL
REPRESENT TEMPERATURE ANOMALIES BETWEEN 20-35 DEGREES BELOW
AVERAGE. WIDESPREAD LOW DAILY MAX TEMPERATURE RECORDS MAY BE TIED
OR BROKEN FROM THE OHIO VALLEY TO THE NORTHEAST/MID-ATLANTIC TODAY
AND TOMORROW. IN STARK CONTRAST TO THE COOL CONDITIONS OVER THE
NORTHEAST, WARM WEATHER (DAYTIME HIGHS 10-15 DEGREES ABOVE
AVERAGE) WILL CONTINUE ACROSS THE SOUTHERN AND WESTERN U.S. OVER
PORTIONS OF SOUTH AND WEST TEXAS, DAYTIME HIGHS CREEPING INTO THE
TRIPLE DIGITS MAY TRANSLATE TO MODERATE TO LOCALLY MAJOR HEATRISK
IMPACTS THROUGH SATURDAY.
