Area forecast discussion, Apr 29, 9:28 AM MST, 1 hour 32 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TUCSON AZ 928 AM MST THU APR 29 2004 SOUTHEAST ARIZONA FORECAST DISCUSSION .SYNOPSIS...A STRONG COLD FRONT OVER NORTHWEST ARIZONA WILL SWEEP ACROSS THE REST OF THE STATE BY THIS EVENING. AS THIS FRONT AND ASSOCIATED LOW PRESSURE SYSTEM MOVES EAST ON FRIDAY...A RIDGE OF HIGH PRESSURE WILL BUILD BACK IN FROM THE WEST...RESULTING IN AFTERNOON TEMPERATURES SOARING BACK TO ABOVE SEASONAL NORMALS. && .DISCUSSION...MID SHIFT LEFT US IN GOOD SHAPE TO DO WHAT WERE ABOUT TO DO, AND THAT IS RAISE HIGH WIND WARNINGS FOR THE E 1/2 OF THE CWA. WE WERE AFRAID A COUPLE OF DAYS AGO THAT IF THE FRONT SLOWED DOWN, THE HIGHEST WINDS COULD END UP OVER OUR CWA. UNFORTUNATELY, THAT IS COMING TO PASS. COLD FRONT AT 16Z EXTENDED FROM KPRC TO JUST W OF KGBN WILL ENTER THE KTUS AREA RIGHT AROUND 21Z AND THE NM BORDER AROUND 00Z. 12Z SOUNDING SHOWED 50KTS JUST ABOVE 700MB WITH THE 90KT UPPER JET ABOUT TO ROUND THE BASE OF THE TROUGH AND CROSS CENTRAL AZ THIS AFTERNOON/EVENING. THE JET IS IS ALSO RATHER LOW IN THE TROPOSPHERE (400MB) WITH SOME EVIDENCE OF A DEEPENING TROPOPAUSE FOLD. THUS, OUR ALREADY TIGHT GRADIENT WILL TIGHTEN A LITTLE MORE. IN ADDITION, MODELS SHOWS 500MB TEMPS DROPPING A DEGREE OR TWO WITH THE FRONT WHICH WILL AID IN CONVECTIVE OVERTURNING. ONE MINUS TO REALLY HIGH WINDS WILL BE THE DECENT UPWARD MOTION ACCOMPANYING THE FRONT. THAT MAY SPARE THE LOWER DESERTS FROM FULL MIXING POTENTIAL. HOWEVER, IT MAY HELP THE WHITES THIS AFTERNOON SINCE ANY TSTMS THAT MANAGE TO DEVELOP WILL ONLY AID IN THE MOMENTUM TRANSFER DOWN TO THE MOUNTAINTOPS. ONLY OTHER TWEAK TO THE FORECAST, GIVEN THE SOMEWHAT SLOWER TIMING OF THE FRONT, WILL BE TO RAISE HIGHS A NOTCH OVER THE E CWA. REST OF THE FORECAST IS IN FINE SHAPE WITH MODELS. ONLY MINOR ISSUE ON FRI MAY BE SOME AFTERNOON BREEZINESS UP THE SAFFORD VALLEY, ESPECIALLY IN THE LOW DOESNT EJECT AS FAST AS THE MODELS CURRENTLY SUGGEST. && .FIRE WEATHER...STRONG AGEOSTROPHIC S FLOW HAS KEEP AT LEAST A LITTLE MOISTURE FLOWING N INTO THE CWA. STRONG AND VERY DEEP MIXING WILL KEEP THE DEWPOINTS LOW ENOUGH, THOUGH, FOR HUMIDITIES TO DROP BELOW 15% IN THE DESERTS AND VALLEYS. RED FLAG WARNING IS WELL PLACED. WE WILL HAVE TO KEEP AN EYE ON FRI IN THE E CWA IF THE LOW IS SLOW TO EJECT, BUT INITIAL THOUGHT IS THAT TEMPS WILL BE QUITE A BIT COOLER WHICH WILL KEEP THE RHS UP AND WILL PREVENT FULL MIXING LIKE WERE SEEING TODAY. && .TWC WATCHES/WARNINGS/ADVISORIES... HIGH WIND WARNING UNTIL 7 PM ZONES 19/EASTERN 29/30/33/34/35 WIND ADVISORY UNTIL 7 PM ZONES WESTERN 29/31/32 RED FLAG WARNING UNTIL 7PM ZONES EASTERN 147/148 AND BELOW 6000 FEET IN ZONE 146. && PYTLAK
