..NO SEVERE THUNDERSTORM AREAS FORECAST
..SUMMARY
SEVERE THUNDERSTORM POTENTIAL APPEARS LOW ON FRIDAY.
..SYNOPSIS
A MID/UPPER-LEVEL LOW AND ATTENDANT TROUGH INITIALLY NEAR THE
PACIFIC COAST ARE FORECAST TO MOVE EASTWARD FRIDAY. IN ADVANCE OF
THIS SYSTEM, NHC IS FORECASTING TROPICAL CYCLONE PRISCILLA TO WEAKEN
AS IT MOVES NORTHWARD AND APPROACHES BAJA CALIFORNIA. MOISTURE
RELATED TO PRISCILLA WILL CONTINUE TO STREAM NORTHWARD INTO PARTS OF
THE SOUTHWEST AND GREAT BASIN. A COMBINATION OF THE EASTWARD-MOVING
TROUGH AND NORTHWARD-MOVING MOISTURE WILL RESULT IN A BROAD REGION
OF AT LEAST ISOLATED STORM POTENTIAL FROM THE SOUTHWEST/GREAT BASIN
INTO PARTS OF THE NORTHWEST AND NORTHERN ROCKIES. WHILE MODERATE TO
LOCALLY STRONG MID/UPPER-LEVEL FLOW WILL OVERSPREAD MUCH OF THE
REGION, WEAK INSTABILITY IS CURRENTLY EXPECTED TO LIMIT SEVERE
POTENTIAL.
MORNING ELEVATED CONVECTION RELATED TO A MID/UPPER-LEVEL LOW/TROUGH
MOVING ACROSS THE GREAT LAKES MAY CONTINUE EARLY IN THE PERIOD FROM
THE LOWER MO VALLEY VICINITY INTO THE UPPER MIDWEST. SOME MOISTURE
INITIALLY TRANSPORTED NORTHWARD BY THE GREAT LAKES SYSTEM MAY ADVECT
WESTWARD INTO PARTS OF THE CENTRAL HIGH PLAINS AND SUPPORT ISOLATED
STORM DEVELOPMENT WITHIN A POST-FRONTAL REGIME.
A GRADUALLY AMPLIFYING MID/UPPER-LEVEL TROUGH ACROSS THE SOUTHEAST
WILL SUPPORT OCCASIONAL STORM DEVELOPMENT FROM THE FL PENINSULA TO
NEAR/JUST OFFSHORE OF THE CAROLINA COAST. POOR MIDLEVEL LAPSE RATES
AND GENERALLY MODEST BUOYANCY AND DEEP-LAYER SHEAR ARE EXPECTED TO
HAMPER ORGANIZED-SEVERE POTENTIAL.
