0458 AM CST TUE MAR 03 2026
AREAS AFFECTED...PARTS OF THE MID-ATLANTIC INTO THE NEW YORK METRO
AREA.
CONCERNING...WINTER MIXED PRECIPITATION
VALID 031058Z - 031600Z
SUMMARY...AN AREA OF FREEZING RAIN, WITH SOME SNOW ON THE NORTHERN
EXTENT, CONTINUES THIS MORNING.
DISCUSSION...A PRECIPITATION SHIELD IS EXPANDING ACROSS THE
MID-ATLANTIC THIS MORNING AS ISENTROPIC ASCENT INCREASES. AREA VWPS
AT LWX, CCX, AND PBZ HAVE SAMPLED INCREASING 1-2 KM FLOW OVER THE
PAST FEW HOURS TO NEAR 35 TO 40 KNOTS. EVEN STRONGER FLOW (~45
KNOTS) IS EVIDENT ON THE RLX VWP. THIS STRONGER FLOW WILL SPREAD
NORTHEASTWARD THROUGH THE MORNING AND WILL RESULT IN GREATER
PRECIPITATION RATES. MOSTLY FREEZING RAIN, WITH SOME SNOW IS BEING
OBSERVED THIS MORNING ACROSS THE REGION. ACROSS NORTHERN VIRGINIA
AND MARYLAND, WHERE TEMPERATURES ARE CURRENTLY NEAR 32F, EXPECT A
TRANSITION TO MOSTLY RAIN RELATIVELY SOON AS SOUTHERLY FLOW
STRENGTHENS THIS MORNING. FARTHER NORTH ACROSS PENNSYLVANIA, EXPECT
THE FREEZING RAIN TO PERSIST INTO THE MORNING WHERE WET-BULB
TEMPERATURES ARE IN THE 20S. ACROSS EASTERN PENNSYLVANIA INTO
NORTHERN NEW JERSEY AND SOUTHERN NEW YORK, TEMPERATURES WILL STAY
WELL BELOW FREEZING THROUGH THE MORNING. FORECAST SOUNDINGS INDICATE
PRECIPITATION MAY BE PRIMARILY SNOW INITIALLY WITH A FEW HOUR
TRANSITION TO FREEZING RAIN BY LATE MORNING.
