DISCUSSION
THE PRIMARY WEATHER CONCERN TODAY IS THE THREAT FOR
STRONG TO ISOLATED SEVERE THUNDERSTORMS. SUBTROPICAL MOISTURE
ASSOCIATED WITH THE NORTH AMERICAN MONSOON CONTINUES TO SURGE
INTO THE REGION, WITH HIGH ATMOSPHERIC MOISTURE PROVIDING PLENTY
OF FUEL FOR THUNDERSTORM DEVELOPMENT. THUNDERSTORMS WILL MOVE
SOUTH TO NORTH, WITH THE HIGHEST LIGHTNING RISK BETWEEN 500-900PM
MDT. THERE IS A 70% CHANCE FOR WIND GUSTS OF 35 MPH OR GREATER
WITH STORMS THIS EVENING AND A 5% CHANCE FOR GUSTS OF 60 MPH OR
HIGHER. LOOKING AHEAD TO THIS WEEKEND, SHOWER AND THUNDERSTORM
ACTIVITY WILL DECREASE TO ISOLATED COVERAGE ON SATURDAY. DRIER AIR
MOVES IN SUNDAY INTO MONDAY, LEADING TO MOSTLY SUNNY SKIES.
HEAT REMAINS A CONCERN EACH DAY THROUGH JUNE 21ST AS TEMPERATURES
RUN 5-10 DEGREES ABOVE NORMAL. HIGH TEMPERATURES WILL REACH INTO
THE MID-UPPER 90S EACH AFTERNOON.
