SPOT FORECAST FOR HOT SPRINGS
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
205 PM MDT SUN JUL 25 2010

...FIRE WEATHER WATCH FOR DRY LIGHTNING AND MICROBURST WINDS
FROM NOON TO 10 PM MDT MONDAY...

.DISCUSSION...DAYTIME HEATING THIS AFTERNOON WILL RESULT IN AN
INCREASE IN THE NUMBER OF BUILDUPS AROUND THE AREA...WITH A
SMALL CHANCE ONE OR TWO OF THESE DEVELOP INTO THUNDERSTORMS.
ANY STORMS WHICH DEVELOP WILL REMAIN DRY WITH STRONG AND
ERRATIC MICROBURST WINDS POSSIBLE.

HIGH PRESSURE CENTERED ACROSS THE AREA TODAY WILL MOVE EAST
TONIGHT...ALLOWING A SOUTHWESTERLY FLOW TO DEVELOP BY MONDAY.
THIS FLOW WILL QUICKLY TRANSPORT MOISTURE INTO THE AREA
THROUGHOUT THE DAY MONDAY. THUNDERSTORMS ARE EXPECTED TO DEVELOP
MONDAY AFTERNOON AND EVENING AS THIS MOISTURE SPREADS NORTHWARD.
THE INITIAL ROUND OF STORMS WILL LIKELY REMAIN DRY...WITH DRY
LIGHTNING AND MICROBURST WINDS POSSIBLE.

THIS MOISTURE WILL QUICKLY INCREASE MONDAY NIGHT INTO
TUESDAY...ALLOWING THUNDERSTORMS TO TRANSITION FROM DRY TO
WET...AS WELL AS ALLOWING FOR HIGHER AFTERNOON RH VALUES AND
BETTER OVERNIGHT RECOVERY. DEEP MOISTURE LOOKS TO REMAIN IN
PLACE THROUGH MUCH OF THE UPCOMING WEEK...RESULTING IN A GOOD
CHANCE FOR SHOWERS AND THUNDERSTORMS EACH AFTERNOON/EVENING.
HEAVY RAINFALL WILL BE POSSIBLE WITH THESE STORMS.
