...WARMING TREND FOR THE EAST, WHILE MUCH COOLER TEMPERATURES
SPREAD FROM THE ROCKIES INTO THE NORTHERN AND CENTRAL PLAINS...
...HEAVY RAINS POSSIBLE ACROSS THE SOUTHWEST SUNDAY NIGHT INTO
MONDAY AND ACROSS CENTRAL TO SOUTH FLORIDA THROUGH TUESDAY...
...WIDESPREAD HEAVY RAIN/FLOODING THREAT DEVELOPING FROM THE
SOUTHERN TO CENTRAL PLAINS INTO THE MID MISSISSIPPI VALLEY...
SIGNIFICANT CHANGES TO THE LARGE SCALE FLOW PATTERN EXPECTED OVER
THE NEXT FEW DAYS, WITH VERY ACTIVE HEAVY RAIN POTENTIAL IN
SEVERAL SECTIONS OF THE NATION. THE DEEP UPPER TROF THAT HAS KEPT
TEMPERATURES WELL BELOW AVERAGE OVER THE PAST SEVERAL DAYS ACROSS
THE EASTERN U.S., WILL BE PUSHING OFF THE EAST COAST LATE MONDAY
INTO TUESDAY. THIS WILL BE REPLACED BY A BUILDING UPPER RIDGE AND
SUPPORT MUCH WARMER TEMPERATURES FOR THE EARLY AND MIDDLE PART OF
THE NEW WEEK FOR MOST AREAS TO THE EAST OF THE MISSISSIPPI RIVER.
THE BUILDING UPPER RIDGE ACROSS THE EAST WILL BE THE NORTHERN
COMPONENT OF A DEVELOPING REX BLOCK ALONG THE EAST COAST. THE
SOUTHERN PORTION OF THIS BLOCK WILL BE COMPRISED OF A DEVELOPING
UPPER LOW ACROSS THE CENTRAL TO EASTERN GULF AND FLORIDA. THIS
UPPER LOW, AND A STATIONARY FRONTAL BOUNDARY AT THE SURFACE ACROSS
CENTRAL FLORIDA WILL SUPPORT HEAVY RAIN POTENTIAL FOR CENTRAL TO
SOUTHERN FLORIDA OVER THE NEXT FEW DAYS. MUCH OF FLORIDA IS
COMING OUT OF THE DRY SEASON WITH SEVERE TO EXTREME DROUGHT
CONDITIONS, WITH THE UPCOMING HEAVY RAIN POTENTIAL MUCH WELCOMED
HYDROLOGICALLY. THIS HEAVY RAIN POTENTIAL WILL ALSO POSE A
FLOODING THREAT, PRIMARILY IN THE URBANIZED AREAS OF CENTRAL TO
SOUTHERN FLORIDA OVER THE NEXT FEW DAYS.
ACROSS THE MIDDLE PORTION OF THE NATION, BIG TEMPERATURE CHANGES
ALSO ON TAP WITH MUCH COOLER TEMPERATURES DEVELOPING FROM THE
ROCKIES INTO THE PLAINS OVER THE NEXT FEW DAYS. THIS WILL BE IN
RESPONSE TO A STRONG COLD FRONT PUSHING EAST INTO THE NORTHERN
PLAINS TONIGHT AND MONDAY, SOUTHWARD INTO THE CENTRAL PLAINS BY
EARLY TUESDAY AND INTO THE SOUTHERN PLAINS BY WEDNESDAY. THIS
FRONT WILL BE THE FOCUS FOR AN EXPANDING AREA OF HEAVY RAINS AS
ABOVE AVERAGE MOISTURE VALUES FROM THE SUB-TROPICAL EASTERN
PACIFIC ARE DRAWN NORTHEASTWARD ALONG THIS FRONTAL BOUNDARY. THIS
NORTHEASTWARD PUSH OF ABOVE AVERAGE MOISTURE VALUES WILL INITIALLY
PRODUCE HEAVY RAINS AND LOCALIZED FLOODING THREATS FROM LATE
SUNDAY AFTERNOON INTO MONDAY ACROSS THE SOUTHWEST INTO THE EASTERN
GREAT BASIN AND SOUTHERN TO CENTRAL ROCKIES. THIS ABOVE AVERAGE
MOISTURE WILL THEN STREAM NORTHEASTWARD ALONG THE ABOVE MENTIONED
STRONG FRONT, SUPPORTING AN EXPANDING AREA OF HEAVY RAIN POTENTIAL
LATE MONDAY THROUGH TUESDAY ACROSS THE CENTRAL TO SOUTHERN PLAINS.
THESE HEAVY RAINS WILL BRING SOME DROUGHT RELIEF TO PORTIONS OF
THE CENTRAL PLAINS AND ADDITIONAL HEAVY RAINS OVER THE SOUTHERN
PLAINS INTO THE MID MISSISSIPPI VALLEY THAT HAVE SEEN MUCH ABOVE
AVERAGE PRECIPITATION OVER THE PAST MONTH. THE HEAVY RAIN THREAT
ACROSS THE CENTRAL TO SOUTHERN PLAINS WILL ALSO BE ACCOMPANIED BY
AN INCREASING SEVERE WEATHER THREAT, WITH HIGH WINDS AND LARGE
HAIL THE GREATEST SEVERE WEATHER THREAT, WITH A LESSER THREAT OF
TORNADOES.
