Area forecast discussion, Aug 5, 5:32 AM MDT, 3 hours 21 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
532 AM MDT WED AUG 5 2009
.SYNOPSIS...A LOW PRESSURE SYSTEM OFF THE CALIFORNIA COAST THIS
MORNING WILL MOVE INLAND EARLY THURSDAY. INCREASING SOUTHERLY FLOW
AHEAD OF THE APPROACHING LOW WILL DRAW MOISTURE INTO UTAH AND
PRODUCE STRONG SOUTHERLY SURFACE WINDS TODAY THROUGH THURSDAY. COOLER
TEMPERATURES WILL SPREAD ACROSS THE STATE FRIDAY THROUGH SATURDAY.
&&
.DISCUSSION...THE LARGE SCALE PATTERN ACROSS THE WRN STATES THROUGH
ERN PACIFIC HAS CHANGED LITTLE OVER THE PAST 24 HOURS. LOW PRESSURE
ALONG THE NRN CA COAST WITH THE UPPER HIGH CENTERED OVER NEW MEXICO
CONTINUE TO PUMP MOISTURE NORTHWARD INTO UTAH THIS MORNING. THE
INCREASE IN MOISTURE HAS BEEN SLOW AND AT THE MID-LEVELS
OVERNIGHT...WITH THE DEEP LAYER MOISTURE REMAINING WELL SOUTH OVER
SRN AZ/NWRN MEXICO. WILL INTRODUCE A BIT MORE CONVECTION TO THE
FORECAST THIS AFTERNOON...THOUGH WILL KEEP THE AREAL COVERAGE
MINIMAL AGAIN TODAY.
THE COASTAL CA UPPER LOW STILL ON TRACK TO MOVE EAST INTO NRN CA
LATE TONIGHT...THEN EAST INTO THE WRN GREAT BASIN TONIGHT. FROM
THERE THE UPPER LOW WILL SLOWLY WIND DOWN AS IT LIFTS E-NE ACROSS
THE NRN GREAT BASIN/NRN ROCKIES FRIDAY THROUGH FRIDAY NIGHT. THE
ASSOCIATED SURFACE FRONT IS AGAIN RUNNING WELL AHEAD OF THE UPPER
LOW IN THE MODEL GUIDANCE FROM THE 00Z RUN. THE FRONT IS NOW
SCHEDULED TO CROSS WRN/NRN UTAH THURSDAY EVENING...WITH THE REMNANT
OF THE UPPER LOW FOLLOWING FRIDAY. LIMITED MOISTURE AND MARGINAL
BAROCLINIC STRUCTURE NOTWITHSTANDING...COULD STILL SEE THIS SYSTEM
PRODUCING AT LEAST SCATTERED CONVECTIVE PRECIP ACROSS THE NRN
THIRD OF THE STATE FRIDAY THROUGH EARLY FRIDAY. DECENT DYNAMIC
LIFT AND DEEP LAYER UNSEASONABLY COLD AIR ALOFT SUGGEST THAT THIS
SYSTEM COULD PRODUCE RESPECTABLE UPWARD MOTIONS TO OVERCOME THE
LIMITED MOISTURE AND PRODUCE PRECIP. WILL KEEP POPS UP NORTH IN
THE FORECAST...WITH SCATTERED COVERAGE POSSIBLE.
A TRAILING SECONDARY SHORTWAVE COULD KEEP SOME PRECIP GOING OVER
THE FAR NORTH SATURDAY. TEMPERATURES STATEWIDE WILL BE NOTICEABLY
COOLER...ESPECIALLY UP NORTH WHERE READINGS WILL BE AROUND 5-15
DEGREES BELOW NORMAL FOR EARLY AUGUST. BUILDING HEIGHTS
SUNDAY/MONDAY WILL BRINGS TEMPS BACK UP AND FORCE ANY LINGERING
PRECIP NORTH OF THE STATE.
THE LATEST VERSIONS OF THE ECMWF AND GFS DO DIFFER TOWARDS THE
MIDDLE OF NEXT WEEK. THE GFS BRINGS A PROGRESSIVE AND ENERGETIC
TROUGH THROUGH SRN CANADA/NRN ROCKIES...WHILE THE ECMWF HOLDS THE
TROUGH BACK OFF THE PACIFIC NW/BRITCOL COAST. INCLINED TO THINK IN
EARLY AUGUST THAT HIGHER HEIGHTS WILL PREVAIL OVER THE INTERIOR
WEST...WHICH WOULD KEEP THE TROUGH EITHER BACK NEAR THE COAST LIKE
THE ECMWF SOLUTION...OR WOULD FORCE THE WESTERLY MUCH FURTHER TO
OUR NORTH. IN EITHER CASE WILL KEEP TEMPS SEASONALLY WARM WITH
LITTLE THREAT FOR PRECIP LATE IN THE EXTENDED FORECAST PERIOD.
&&
.AVIATION...SURFACE WINDS AT THE SLC TERMINAL WILL REMAIN SOUTHERLY
THROUGH TODAY WITH GUSTS OVER 25 KTS POSSIBLE BETWEEN 20 AND 01Z.
THERE IS LESS THAN A 10 PERCENT CHANCE OF A THUNDERSTORM DIRECTLY
IMPACTING THE TERMINAL BETWEEN 18Z AND 23Z.
&&
.FIRE WEATHER...SOUTH WINDS AND LOW RH WILL COMBINE OVER THE WESTERN
MOST FIRE WEATHER ZONES FROM IRON COUNTY NORTHWARD TODAY. ALTHOUGH
WINDS WILL RELAX TONIGHT AND RELATIVE HUMIDITY INCREASE OVER 15
PERCENT THE WINDS WILL SET BACK IN THURSDAY AND BECOME VERY STRONG
ALONG WITH LOW RH. WINDS WILL INCREASE OVER THE ENTIRE REGION
THURSDAY BUT THERE IS A POSSIBILITY OF HIGHER RH ALONG THE COLORADO
BORDER SO A WATCH WILL REMAIN IN EFFECT THERE. A COLD FRONT WILL
MOVE INTO THE NORTHWEST PORTIONS THURSDAY EVENING AND ACROSS THE
REST OF THE AREA FRIDAY. THE RH WILL COME UP BEHIND THIS FRONT IN
THE NORTH BUT REMAIN LOW ACROSS THE SOUTH SO SEVERE FIRE WEATHER
CONDITIONS ARE LIKELY THROUGH FRIDAY IN THE SOUTH.
