SPC MD 89
MD 0089 CONCERNING FREEZING RAIN FOR NORTHERN VERMONT...NORTHERN NEW
HAMPSHIRE...PORTIONS OF WESTERN AND CENTRAL MAINE
MESOSCALE DISCUSSION 0089
NWS STORM PREDICTION CENTER NORMAN OK
0700 PM CST WED JAN 24 2024
AREAS AFFECTED...NORTHERN VERMONT...NORTHERN NEW
HAMPSHIRE...PORTIONS OF WESTERN AND CENTRAL MAINE
CONCERNING...FREEZING RAIN
VALID 250100Z - 250500Z
SUMMARY...FREEZING RAIN ACCUMULATIONS AROUND 0.01-0.03 PER PER HOUR
LIKELY THROUGH THE EVENING.
DISCUSSION...FREEZING RAIN ACCUMULATIONS OF 0.01-0.03" HAVE BEEN
REPORTED ACROSS UPSTATE NEW YORK OVER THE LAST HOUR, WITH FREEZING
RAIN BEING REPORTED AT SEVERAL STATIONS ACROSS PORTIONS OF VERMONT
AND NEW HAMPSHIRE. THIS THREAT WILL LIKELY SHIFT EASTWARD INTO
WESTERN MAINE OVER THE NEXT FEW HOURS. THE OBSERVED 00Z SOUNDING
FROM GYX SHOWS THE PROFILE IS LARGELY BELOW ZERO FROM THE SURFACE TO
JUST ABOVE 850 MB. STRONG WARM AIR ADVECTION IS ONGOING IN LOW TO
MID-LEVEL WEST TO SOUTHWESTERLY FLOW FROM 850-500 MB. THIS IS
FURTHER SUPPORTED IN RAP FORECAST SOUNDINGS INDICATING WARMING ABOVE
THE SURFACE SHOULD SUPPORT THE DOWNSTREAM THREAT OF FREEZING RAIN AS
THE HEAVIER PRECIPITATION ARRIVES NORTHEASTWARD. AREAS ACROSS THE
HIGHER TERRAIN OF THE WHITE MOUNTAINS WILL LIKELY SEE SNOW, WITH THE
BEST POTENTIAL FOR FREEZING RAIN ACCUMULATIONS LOCATED ACROSS THE
LOWER VALLEYS.

NWS STORM PREDICTION CENTER NORMAN OK
0645 PM CST WED JAN 24 2024
VALID 250100Z - 251200Z
...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM PARTS OF
SOUTHERN AND SOUTHEASTERN TEXAS TOWARD THE NORTHERN GULF COAST
THROUGH TONIGHT...
...SUMMARY...
ISOLATED SEVERE THUNDERSTORMS REMAIN POSSIBLE THROUGH TONIGHT FROM
SOUTH TEXAS TO THE CENTRAL GULF COAST REGION.
...SOUTHERN TX TO THE NORTHERN GULF COAST...
A FRONT CURRENTLY STRETCHES FROM NEAR BROWNSVILLE TX NORTHEASTWARD
ACROSS THE GULF OF MEXICO AND INTO SOUTHEAST LA. NOTABLY WEAK
SOUTHERLY FLOW WILL PERSIST SOUTH OF AND NEAR THIS FRONT AS AN UPPER
TROUGH MOVES ACROSS TX. OVERALL ADVECTION OF MOISTURE AND
INSTABILITY IS FORECAST TO REMAIN MINIMAL, BUT SOME RECOVERY IS
POSSIBLE OVER PARTS OF SOUTHERN LA AND COASTAL MS/AL LATE TONIGHT.
THE AIR MASS NEAR THIS FRONT MAY SUPPORT SURFACE-BASED CONVECTION,
ALTHOUGH EFFECTIVE SRH WILL REMAIN MARGINAL FOR SUPERCELL OR TORNADO
THREAT. FOR NEAR-TERM INFORMATION, SEE MESOSCALE DISCUSSION 88.
TO THE WEST, COOLING ALOFT AND LIFT WITH THE UPPER TROUGH MAY
INTERACT WITH ELEVATED INSTABILITY ROOTED ABOVE 850 MB TO SUPPORT
MARGINALLY SEVERE HAIL OVER PARTS OF SOUTHERN AND SOUTHEASTERN TX
TONIGHT, SUPPORTED BY LONG HODOGRAPHS. STORMS ARE EXPECTED TO FOR
NEAR THE RIO GRANDE VALLEY LATE THIS EVENING, AND SPREAD RAPIDLY
EASTWARD TOWARD THE SABINE VALLEY BY 12Z THURSDAY.
