...RED FLAG WARNING IN EFFECT FROM NOON TO 10 PM MDT TUESDAY FOR
WIND AND LOW RELATIVE HUMIDITY FOR FIRE WEATHER ZONES 493, 494, 496,
AND 498...
...DRY LIGHTNING POTENTIAL WEDNESDAY, FOLLOWED BY STRONG SOUTHWEST

BROADCAST DISCUSSION
HOT AND VERY DRY CONDITIONS WILL CONTINUE
THROUGH MIDWEEK. MOISTURE WILL TEMPORARILY SPREAD INTO SOUTHERN,
CENTRAL AND POTENTIALLY NORTHERN UTAH WEDNESDAY ACCOMPANIED BY A
CHANCE OF THUNDERSTORMS. STRONG SOUTHWEST WINDS AND VERY LOW RH
WILL FOLLOW ACROSS THE REGION FRIDAY INTO SATURDAY, WITH A STRONG
COLD FRONTAL PASSAGE EXPECTED LATER SATURDAY.
DISCUSSION
A HOT AND DRY AIRMASS WILL REMAIN IN PLACE ACROSS THE
STATE THROUGH TUESDAY, AS DAYTIME TEMPERATURES CONTINUE TO RUN 5 TO
10 DEGREES ABOVE NORMAL FOR THE LATTER HALF OF JUNE. AFTERNOON RH
WILL REMAIN BELOW 15 PERCENT ACROSS NEARLY ALL ELEVATIONS BELOW
8000 FEET THROUGH TUESDAY, WITH OVERNIGHT RECOVERY MARGINAL TO
POOR IN THE NORTH, AND NEARLY NON-EXISTANT ACROSS MUCH OF SOUTHERN
UTAH. GUSTY WEST WINDS WILL TREND A LITTLE STRONGER TUESDAY
ACROSS SOUTH CENTRAL AND SOUTHEAST UTAH, WHICH PROMPTED THE
ISSUANCE OF A RED FLAG WARNING FOR ZONES 493, 494, 496 AND 498.
MOISTURE WILL SPREAD NORTHWARD INTO SOUTHERN, CENTRAL AND
POTENTIALLY PORTIONS OF NORTHERN UTAH WEDNESDAY, BRINGING A
CHANCE FOR SHOWERS AND THUNDERSTORMS. INITIALLY THESE STORMS WILL
LIKELY BE HIGH BASED WITH DRY LIGHTNING AND STRONG OUTFLOWS A
THREAT. HOWEVER, A QUICK TRANSITION FROM DRY TO A MIXTURE OF WET
AND DRY STORMS MAY OCCUR WEDNESDAY AFTERNOON/EVENING,
PARTICULARLY ACROSS SOUTHERN UTAH. GIVEN THIS UNCERTAINTY HAVE
HELD OFF ON A FIRE WEATHER WATCH AT THIS TIME. THIS MOISTURE LOOKS
TO BE SWEPT OUT OF THE AREA DURING THE DAY THURSDAY, AS A GENERAL
SOUTHWESTERLY FLOW DEVELOPS ACROSS THE REGION.
A POTENTIALLY SIGNIFICANT PERIOD OF CRITICAL FIRE WEATHER
CONDITIONS IS LOOKING MORE LIKELY FRIDAY INTO SATURDAY, AS STRONG
SOUTHWESTERLY FLOW ALONG WITH A VERY DRY AIRMASS SPREAD ACROSS THE
STATE, AHEAD OF AN APPROACHING COLD FRONT. WIND GUSTS FRIDAY LOOK
LIKELY TO REACH THE 40 MPH RANGE ACROSS WESTERN UTAH. AS THE FRONT
APPROACHES, AND EVENTUALLY CROSSES UTAH SATURDAY, THESE WIND GUSTS
MAY REACH 50 MPH AT TIMES ACROSS CENTRAL AND SOUTHERN UTAH
SATURDAY AFTERNOON. THERE IS SOME UNCERTAINTY WITH FRONTAL TIMING
WHICH WILL DETERMINE HOW FAR NORTH THESE STRONG WINDS EXTEND
SATURDAY, BUT LOOK MOST LIKELY SOUTH OF THE I-70/US-50 CORRIDOR.
AS THIS FRONT SWEEPS THROUGH THE REGION, MUCH COOLER TEMPERATURES
WILL FOLLOW FOR SUNDAY.
***THUNDERSTORMS IMPLY STRONG, GUSTY AND ERRATIC WINDS***
