SHORT RANGE FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
253 AM EDT MON APR 22 2024
VALID 12Z MON APR 22 2024 - 12Z WED APR 24 2024
...SHOWER AND THUNDERSTORM CHANCES STRETCH FROM THE UPPER MIDWEST
AND GREAT LAKES TO THE SOUTHERN PLAINS OVER THE NEXT FEW DAYS...
...CHILLY AND FROSTY START TO EARTH DAY THROUGHOUT THE OHIO VALLEY
AND MID-ATLANTIC, WHILE WELL ABOVE AVERAGE TEMPERATURES REMAIN IN
PLACE ACROSS MUCH OF THE SOUTHWEST/GREAT BASIN...
PRECIPITATION CHANCES ARE EXPECTED TO REMAIN MOSTLY SCATTERED AND
LIGHT THROUGHOUT MUCH OF THE NATION INTO MIDWEEK AS ATMOSPHERIC
MOISTURE CONTENT REMAINS SPARSE FOLLOWING THE PASSAGE OF A STRONG
COLD FRONT INTO THE GULF OF MEXICO AND WESTERN ATLANTIC. A FEW
THUNDERSTORMS ARE POSSIBLE ACROSS THE CENTRAL AND SOUTHERN FLORIDA
PENINSULA TODAY AS THE AFOREMENTIONED COLD FRONT MAKES IT'S FINAL
EXIT. A FEW STORMS COULD TURN SEVERE AND PRODUCE DAMAGING WIND
GUSTS AND HAIL. THUS, THE STORM PREDICTION CENTER HAS ISSUED A
MARGINAL RISK (LEVEL 1/5) FOR SEVERE WEATHER ACROSS SOUTHEAST
FLORIDA. OTHERWISE, RAIN CHANCES ARE FORECAST TO PROGRESS EASTWARD
FROM THE NORTHERN PLAINS TO THE UPPER MIDWEST TODAY ALONG A
SWIFTLY MOVING PACIFIC COLD FRONT. BY TUESDAY, RAIN CHANCES ARE
ANTICIPATED TO STRETCH FROM THE GREAT LAKES AND OHIO VALLEY TO THE
SOUTHERN PLAINS. THE HEAVIEST RAIN ASSOCIATED WITH THIS SYSTEM IS
POSSIBLE ACROSS PARTS OF CENTRAL/EASTERN OKLAHOMA AND WESTERN
ARKANSAS ON WEDNESDAY, BUT THIS ASPECT OF THE FORECAST REMAINS
SOMEWHAT UNCERTAIN.
TEMPERATURES ARE EXPECTED TO START OFF IN THE 30S THROUGHOUT MUCH
OF THE MIDWEST, OHIO AND TENNESSEE VALLEYS, MID-ATLANTIC, AND
NORTHEAST AS STRONG HIGH PRESSURE LEADS TO CLEAR SKIES AND COLD
TEMPERATURES AT GROUND-LEVEL. LOWS INTO THE LOW 30S ARE LIKELY TO
LEAD TO FROST/FREEZE CONDITIONS AND HAS PROMPTED FROST ADVISORIES
AND FREEZE WARNINGS FOR MUCH OF THE REGION WHERE THE GROWING
SEASON HAS ALREADY BEGUN. WARMER WEATHER IS FORECAST TO BEGIN
SPREADING EASTWARD ON TUESDAY, BUT WILL BE SHORT-LIVED AS THE NEXT
SHOT OF COLD AIR ENTERS THE GREAT LAKES TUESDAY NIGHT. WARMER
WEATHER IS ANTICIPATED TO REMAIN THROUGHOUT THE SOUTHWEST, GREAT
BASIN, AND PARTS OF THE SOUTHERN PLAINS THROUGH MIDWEEK. HIGHS CAN
BE EXPECTED TO REACH INTO THE 70S AND 80S, WITH 90S AND LOW 100S
IN THE TYPICAL WARM SPOTS THROUGHOUT THE DESERT SOUTHWEST.
