Area forecast discussion, Mar 5, 9:45 AM MST, 3 hours 20 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BOISE ID 945 AM MST MON MAR 5 2012 .DISCUSSION...STRONG WARMING WELL UNDERWAY WITH MID MORNING TEMPERATURES ALREADY A COUPLE DEGREES AHEAD OF READINGS THIS TIME YESTERDAY. WILL UPDATE ZONES NUDGING MAX TEMPERATURES UP A COUPLE MORE DEGREES. THIS WILL PUT THE TREASURE VALLEY ZONES WITHIN STRIKING DISTANCE OF RECORDS OR EQUAL THEM. SOUTHEAST WINDS ALREADY CRANKING UP AND THIS WILL ONLY HELP BOOST TEMPERATURES MORE. OTHERWISE...HIGH CLOUDS WILL PUSH EAST THIS AFTERNOON AHEAD OF STRONG FROPA CURRENTLY IN THE PACNW...BUT THESE CLOUDS SHOULD NOT HINDER WARMING. UPDATE TO ZONES FORTHCOMING. && .AVIATION...VFR TODAY...EXCEPT FOR PATCHY AREAS OF IFR FOG NEAR KMYL THROUGH 18Z. CLOUDS WILL INCREASE AND LOWER AFTER 00Z TUESDAY...WITH INCREASING MVFR SHOWERS AND GUSTY SURFACE WINDS AS A COLD FRONT APPROACHES THE AREA. THIS FRONT WILL PASS THROUGH QUICKLY...REACHING KBKE AT APPROXIMATELY 06Z...AND KBOI AT APPROXIMATELY 09Z TUESDAY. SURFACE WINDS SOUTHEAST TO SOUTHWEST UP TO 20 KTS WITH HIGHER GUSTS TODAY. WINDS ALOFT AT 10K FT MSL...SOUTHWESTERLY...FROM 35 KTS AT 18Z MONDAY....UP TO 50 KTS BY 00Z TUESDAY. && .PREV DISCUSSION...TODAY THROUGH TUESDAY...A LARGE UPPER LEVEL TROUGH CURRENTLY LOCATED NEAR 137W 47N WILL MOVE RAPIDLY SE TOWARD THE AREA TODAY AND TONIGHT. IT WILL MOVE INTO THE CWA ON TUESDAY. A COLD FRONT WILL BE AHEAD OF THE UPPER TROUGH. THIS COLD FRONT WILL MOVE THROUGH TONIGHT...ENTERING SE OREGON THIS EVENING...MAKING IT PAST BURNS AND MCCALL BY MIDNIGHT...MOVING THROUGH THE TREASURE VALLEY BY 3 AM...AND CLEARING THE MAGIC VALLEY BY 6 AM MST. THIS FRONT WILL LIKELY BE ACCOMPANIED BY A LINE OF SHOWERS MUCH LIKE THE ONE THAT MOVED THROUGH ON WED OF LAST WEEK...FEB 29. HOWEVER...THE AIRMASS IS NOT AS COLD NOW AS IT WAS BEFORE THAT SYSTEM MOVED THROUGH. THEREFORE IT IS NOT LIKELY THAT SNOWFALL...OR SNOW PELLETS LIKE LAST TIME...WILL BE ENOUGH TO CAUSE ANY PROBLEMS ON ROADS. WE EXPECT TEMPERATURES AHEAD OF THE LINE TO BE IN THE 40S...DROPPING RAPIDLY TO NEAR FREEZING AFTER THE FRONT GOES THROUGH. AGAIN...ANY SNOWFALL IS UNLIKELY TO BE ABLE TO LAST LONG ON THE WARM ROADS...ESPECIALLY AFTER NEAR RECORD HIGH TEMPERATURES TODAY. TODAY...AHEAD OF THE INCOMING SYSTEM...WE WILL SEE MOSTLY SUNNY SKIES FOR THE MORNING...WITH INCREASING CLOUDS FROM THE NW DURING THE AFTERNOON. SURFACE WINDS WILL BE SOUTHEAST TO SOUTHWEST AS WARM AIR ADVECTION CONTINUES. THIS WILL HELP PUSH TEMPS TO NEAR RECORD MAX TEMPS...AS INDICATED IN PREVIOUS FORECASTS. THE LATEST FORECAST STILL HAS TEMPS NEAR...BUT NOT OVER...RECORDS. ON TUESDAY...AFTER THE FRONT PASSES...VERY STRONG COLD AIR ADVECTION WILL OCCUR. HIGHS ON TUESDAY WILL BE AROUND 10 DEGREES BELOW NORMAL. WINDS THROUGHOUT THE PERIOD WILL BE ABOVE NORMAL. THERE IS A CHANCE FOR ADVISORY-LEVEL WINDS ALONG AND IMMEDIATELY BEHIND THE FRONT AS IT MOVES THROUGH TONIGHT AND EARLY TUESDAY. HOWEVER...AT THIS TIME...IT DOES NOT APPEAR THAT HIGH WINDS WILL LAST LONG ENOUGH TO WARRANT AN ADVISORY. HOWEVER...WINDS GUSTING TO 40 MPH ARE POSSIBLE IF A STRONG LINE OF SHOWERS IS ABLE TO FORM ALONG THE FRONT. AT THIS TIME...WE DO NOT FORESEE ENOUGH SNOWFALL TO WARRANT AN ADVISORY WITHIN THE CWA EITHER. THE SOUTHWEST HIGHLANDS APPEAR TO HAVE THE BEST CHANCE...BUT IT WILL BE MARGINAL. WITH VERY WARM ROADS IN ADVANCE OF THE SNOW...WE HAVE DECIDED AGAINST ISSUING AT THIS TIME. LONG TERM...TUESDAY NIGHT THROUGH SUNDAY...MODEL AGREEMENT IS GOOD THROUGH FRIDAY FOR A SHARPLY AMPLIFIED RIDGE TO BUILD IN OVER THE WEST. THIS WILL MAKE FOR DRY CONDITIONS AND MOSTLY CLEAR SKIES...WITH TEMPERATURES INCREASING EACH DAY. UNCERTAINTY BECOMES HIGH AFTER FRIDAY...AS THE MODELS STRUGGLE WITH THE EVOLUTION OF BOTH UPSTREAM AND DOWNSTREAM SYSTEMS. NEXT SYSTEM WILL AFFECT THE CWA POSSIBLY BY EARLY SATURDAY MORNING...AS A LONG WAVE TROUGH BEGINS TO PUSH TOWARD THE WEST COAST. THEREFORE...THE FORECAST FOR NEXT WEEKEND IS FOR INCREASING CHANCES OF PRECIPITATION...THOUGH WITH MODERATE TEMPERATURES...BEFORE THE TROUGH AND ASSOCIATED COLD AIR REACH THE GREAT BASIN POSSIBLY BY MONDAY. && .BOI WATCHES/WARNINGS/ADVISORIES... ID...NONE. OR...NONE. && WEATHER.GOV/BOISE DISCUSSION...GS PREV DISCUSSION...SP LONG TERM....BB AVIATION.....JDS
