DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1214 PM CDT MON OCT 19 2026
VALID 201200Z - 211200Z
..NO SEVERE THUNDERSTORM AREAS FORECAST
..SUMMARY
NO SEVERE THUNDERSTORMS ARE EXPECTED ON TUESDAY. A FEW STRONG STORMS
MAY AFFECT PARTS OF ARIZONA LATE TUESDAY NIGHT.
..SYNOPSIS
HIGH PRESSURE WILL EXTEND FROM EASTERN CANADA SOUTHWESTWARD TO THE
GULF OF AMERICA ON TUESDAY, MAINTAINING STABLE CONDITIONS OVER MOST
OF THE CENTRAL AND EASTERN STATES ON TUESDAY. FARTHER WEST, A DEEP
UPPER TROUGH WILL EXIST JUST OFF THE WEST COAST, WITH INCREASING
SOUTHWEST WINDS ALOFT FROM CA INTO UT AND AZ.
STRONG DAYTIME HEATING MAY SUPPORT ISOLATED THUNDERSTORMS FROM THE
GREAT BASIN INTO AZ, THOUGH AN INVERSION ABOVE 500 MB SHOULD
MINIMIZE UPDRAFT STRENGTH.
A GREATER CHANCE OF POSSIBLY STRONG THUNDERSTORMS MAY DEVELOP
OVERNIGHT INTO AZ AS TEMPERATURES ALOFT COOL, AND, WINDS INCREASE
OUT OF THE SOUTH. THIS ENHANCED UPSLOPE MAY SUPPORT ADDITIONAL
STORMS ALONG AND NORTH OF THE MOGOLLON RIM, AND SHEAR WILL BE
STRONGER AT THAT TIME. INSTABILITY MAY ONLY BE MARGINALLY
SUPPORTIVE, WITH THE GREATER RISK DEVELOPING AFTER 12Z WEDNESDAY
MORNING.
