AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1020 AM MDT WED JUL 26 2006

.SYNOPSIS...A SLOW WARMING AND DRYING TREND WILL OCCUR THROUGH
FRIDAY AS RIDGE OF HIGH PRESSURE STRENGTHENS TO THE WEST OF THE
AREA. MOISTURE WILL INCREASE OVER THE WEEKEND AS THE RIDGE SLIDES
EAST OF THE AREA BRINGING A SOUTHWEST FLOW ALOFT.

&&

.DISCUSSION...AREA OF CONVECTION EXPANDING SOME OVER PAST HOUR
ACROSS NORTHWEST UTAH INTO SOUTHEAST IDAHO. THIS AREA ASSOCIATED
WITH 60 KT JET THAT IS ROUNDING BASE OF TROUGH MOVING SOUTHEAST
ACROSS IDAHO. THIS TROUGH WILL CONTINUE TO MOVE SOUTHEAST WITH THE
NAM SHOWING A DECENT 300 MB VORT MAX DROPPING RIGHT ACROSS THE
WASATCH FRONT THIS EVENING WHILE THE GFS IS FARTHER EAST TOWARD
VERNAL WITH THIS VORT MAX. CURRENT SATELLITE APPEARS TO SUPPORT THE
FARTHER WEST POSITION OF THE NAM. RADAR LIGHTING UP WITH SCATTERED
SHOWERS AND ISOLATED THUNDERSTORMS. CONSIDERING THE TIME OF DAY THE
UPPER LEVEL DYNAMICS ARE THE MOST LIKELY SUPPORT. WITH THIS IN MIND
HAVE UPDATED NORTHERN ZONES AND SOUTHWEST WYOMING TO INCLUDE
SCATTERED SHOWERS AND THUNDERSTORMS TODAY AND INTO THIS EVENING.
MAY HAVE TO EXPAND THIS FARTHER SOUTH IN AFTERNOON PACKAGE DEPENDING
ON HOW ACTIVITY SHAKES OUT THIS AFTERNOON.

&&

.FIRE WEATHER...RH RECOVERIES A BIT LESS THAN LAST NIGHT. THIS TREND
WILL CONTINUE INTO THE LATTER PART OF THE WEEK AS A LARGE HIGH
PRESSURE RIDGE STRENGTHENS ACROSS THE STATE. A WEAK DISTURBANCE WILL
PUSH INTO NORTHERN UTAH THIS EVENING AND MAY BE A FOCUS FOR
THUNDERSTORMS ACROSS THE NORTHERN UTAH FIRE ZONES. THERE IS ENOUGH
MOISTURE STILL IN PLACE TO HAVE MOSTLY WET THUNDERSTORMS...HOWEVER A
FEW DRY LIGHTNING STRIKES ARE POSSIBLE IN THE INITIAL ROUND OF
STORMS. ELSEWHERE...JUST AFTERNOON AND EARLY EVENING WET
THUNDERSTORMS EXPECTED.

&&

.AVIATION. TROUGH ALOFT MOVING SOUTHEAST ACROSS NORTHERN UTAH THIS
AFTERNOON COULD BE STRONG ENOUGH TO OVERCOME THE STABILITY OF THE
GREAT SALT LAKE. THUNDERSTORMS HAVE DEVELOP NEAR NORTHERN TIP OF THE
LAKE BUT ARE CURRENTLY TRACKING EASTWARD. HOWEVER DEVELOPMENT
FARTHER SOUTH IS LIKELY LATER TODAY AS THE BEST DYNAMICS ALOFT MOVE
FARTHER SOUTH. BEST THREAT OF THUNDERSTORMS WILL BE BETWEEN 22 AND
02Z WITH GUSTY WINDS TO 35 KTS POSSIBLE.
