..RAIN AND SNOW IMPACTS ACROSS CALIFORNIA COME TO AN END TODAY
..ABOVE AVERAGE TEMPERATURES ACROSS THE LOWER 48 INTO LATE WEEK
...CRITICAL FIRE WEATHER DAY OVER PORTIONS OF THE SOUTHERN HIGH
PLAINS ON WEDNESDAY...
RAIN AND SNOW SHOWERS WILL GRADUALLY WEAKEN ACROSS THE STATE OF
CALIFORNIA TODAY BEFORE COMING TO AN END TONIGHT. IN THE MEANTIME,
SNOW SHOWERS WILL PRODUCE 6-12 INCHES OF NEW SNOW FOR THE
INTERMOUNTAIN WEST AND CENTRAL ROCKIES. SURFACE CYCLOGENESIS OVER
THE LEE OF THE ROCKIES WILL SUPPORT STRONG WEST/SOUTHWESTERLY
WINDS CARRYING DRY AIR OUT OF THE SOUTHWEST AND INTO THE SOUTHERN
HIGH PLAINS THIS AFTERNOON. THUS, THE STORM PREDICTION CENTER
ISSUED A CRITICAL RISK OF FIRE WEATHER OVER PORTIONS OF
SOUTHEASTERN NEW MEXICO INTO FAR WESTERN TEXAS.
THE UPPER-LEVEL TROUGH RESPONSIBLE FOR THE UNSETTLED WEATHER IN
THE WEST WILL QUICKLY MOVE ACROSS THE ROCKIES TODAY AND INTO THE
PLAINS BY THURSDAY. THIS WILL SPAWN A LOW PRESSURE SYSTEM OVER THE
CENTRAL/SOUTHERN PLAINS WHICH WILL TAP SOME MOISTURE FROM THE GULF
OF MEXICO AS IT MOVES ACROSS THE MISSISSIPPI VALLEY. THIS
INTERACTION WILL PRODUCE RAIN SHOWERS AND SCATTERED THUNDERSTORMS
ACROSS THE MIDWEST/OHIO VALLEY ON THURSDAY.
MEANWHILE, AN UPPER RIDGE WILL GENERATE TEMPERATURES THAT ARE WELL
ABOVE AVERAGE ACROSS THE PLAINS AND MISSISSIPPI VALLEY TODAY.
TEMPERATURES WILL BE ANYWHERE FROM 20-30 DEGREES ABOVE AVERAGE IN
THESE AREAS. SOUTHERLY FLOW WILL SEND MILD TEMPERATURES STREAMING
INTO THE EAST COAST ON THURSDAY AHEAD OF THE APPROACHING LOW
PRESSURES SYSTEM. THE FLORIDA PENINSULA WILL REMAIN BELOW AVERAGE
TEMPERATURE-WISE THROUGH THE END OF THE WEEK.
