AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GLASGOW MT 840 PM MST MON NOV 12 2007 .SHORT TERM...FOR NORTHEAST MONTANA...TONIGHT THROUGH WEDNESDAY... UPDATE...GUSTY WINDS CONTINUE TO PLAGUE THE TREASURE STATE. VERY DRY AIR HAS DEVELOPED AS THE RESULT OF DOWNSLOPING AND HAS MADE FOR SOME VERY LOW HUMIDITIES ACROSS THE CENTRAL PORTIONS OF THE STATE. WINDS ARE EXPECTED TO DECREASE SOME THIS EVENING...BUT CONTINUE THROUGH THE NIGHT. THIS WILL INHIBIT THE DEVELOPMENT OF A STRONG LOW LEVEL INVERSION AND KEEP TEMPERATURES UP. THUS UPDATED THE FORECAST TO REFLECT WARMER MIN TEMPERATURES TONIGHT. TUESDAY CONTINUES TO LOOK VERY WINDY AS A COLD FRONT COMES SWEEPING THROUGH EARLY ON. GILCHRIST PREVIOUS DISCUSSION...INTENSE STORM SYSTEM HAS NOW MOVED INTO SW CANADA AND IS EXPECTED EXPECTED TO BRING VERY WINDY CONDITIONS TO NORTHEAST MONTANA TUESDAY AFTERNOON. GOING HIGH WIND WATCH LOOKS ON TARGET. MODELS CONTINUE TO AGREE ON HIGH WINDS FOR THE AREA TUESDAY WITH SUPPORTIVE LAPSE RATES...COLD AIR ADVECTION AND STRONG MID LEVEL WINDS. STORM SYSTEM THAT IS BREAKING UP A BIT WILL BE OVER THE PRAIRIE PROVINCES BY LATE TONIGHT. THE SURFACE LOW WILL TRACK EAST INTO CENT SASK BY TUESDAY MORNING AND INTO MANITOBA BY THE AFTERNOON. MUCH OF THE DEEP PACIFIC MOISTURE WILL CONTINUE TO FALL WEST OF THE CONT DIVIDE INTO TUESDAY WITH HIGH AND MID LEVEL CLOUDS STREAMING OVERHEAD. A DRY SLOT SHOULD OPEN UP BY TUESDAY ALLOWING FOR INCREASING SUNSHINE AND MIXING THE ATMOSPHERE TO POSSIBLY 700 MB THE LATE AFTERNOON. WRAP AROUND MOISTURE WILL BE WRAPPED UP WITH THE LOW OVER SOUTH-CENTRAL CANADA TUESDAY. SOME OF THIS MAY WRAP BACK INTO THE CWA AS WINDS BECOMING MORE NORTHERLY. TIME-HEIGHTS ARE SHOWING THIS WITH SOME LOW LEVEL CLOUDINESS MOVING THROUGH WEDNESDAY. THEREFORE...INCREASED SKY AND THE NORTHEAST ZONES MAY REMAIN MOSTLY CLOUDY. MUCH OF THE PRECIPITATION TUESDAY NIGHT IS EXPECTED TO STAY TO OUR NORTHEAST. DIFFICULT TO SAY WHEN WINDS WILL BEGIN BLOWING LATE TONIGHT/TUESDAY MORNING. NAM HAS THE NORTHWEST ZONES APPROACH HIGH WIND CRITERIA FIRST CLOSE TO 6AM WITH THE SE ZONES APPROACHING CRITERIA LATER IN THE MORNING. 850 MB WINDS DECREASE A BIT AT 18Z COMPARED TO 12 ACROSS PARTS OF THE AREA BUT WINDS SHOULD GENERALLY BE STRONGER DURING THE AFTERNOON WITH THE DEEPER MIXING. WILL LET MID SHIFT TAKE ANOTHER LOOK AT LATEST MODELS TO GET BEST ASSESSMENT ON WHERE AND IF HIGH WIND WARNINGS NEED TO BE ISSUED. JAMBA .LONG TERM...WEDNESDAY NIGHT THROUGH MONDAY... THERE IS SOME GENERAL AGREEMENT ON THE PATTERN LATE IN THE WEEK WITH MORE SPREAD IN SOLUTIONS SHOWING UP BY LATE IN THE WEEKEND INTO EARLY NEXT WEEK. IN THE WAKE OF THE STRONG SYSTEM TOMORROW THE CWA LOOKS TO BE UNDER THE INFLUENCE OF SOME SHORTWAVE RIDGING FOR WEDNESDAY NIGHT AND THURSDAY. A WEAK DISTURBANCE MOVING THROUGH CANADA FLATTENS THE RIDGE A BIT FOR THURSDAY NIGHT WITH ANOTHER SHORTWAVE RIDGE ON FRIDAY. THE DISTURBANCE FOR THURSDAY NIGHT LOOKS WEAK AND UNLIKELY TO PRODUCE MORE THAN SOME HIGH OR MID LEVEL CLOUDS. TEMPERATURES THURSDAY WILL BE SEASONABLE AND LIKELY WILL RETURN TO ABOVE AVERAGE LEVELS FRIDAY. THE COOLEST TEMPERATURES BOTH DAYS WILL LIKELY BE ACROSS THE NORTHEAST ZONES CLOSEST TO THE DEPARTING UPPER TROUGH AND IT/S ASSOCIATED COLD POOL THAT WILL SPILL INTO THE GREAT LAKES. BY THE WEEKEND AND INTO NEXT WEEK THERE IS MUCH MORE UNCERTAINTY. THE MODELS APPEAR TO BE STRUGGLING WITH SOME PACIFIC ENERGY AND A TROUGH THAT DEVELOPS SOUTH OF A GULF OF ALASKA LOW. THE ECMWF BRINGS ANOTHER STRONG STORM SYSTEM ACROSS SOUTHERN CANADA EARLY NEXT WEEK AND PULLS SOME COLD AIR DOWN INTO THE AREA IN THE WAKE OF THIS STORM FOR THE MIDDLE OF NEXT WEEK. THE LATEST GFS IS WEAKER WITH THIS SYSTEM...BUT HAS ALSO BEEN SHOWING A LOT OF RUN TO RUN INCONSISTENCIES. GIVEN THE AMOUNT OF UNCERTAINTY WILL NOT BE MAKING ANY SIGNIFICANT CHANGES AS THIS POINT...WHICH WILL AFFORD THE NEXT SHIFT AN OPPORTUNITY TO SEE IF THE MODELS COME INTO BETTER AGREEMENT. BC PREVIOUS LONG TERM... SOME WEAK UPPER RIDGING OVER WESTERN MONTANA WEDNESDAY NIGHT WILL MOVE ACROSS THE AREA ON THURSDAY MORNING...AND IS THEN DAMPENED THURSDAY NIGHT BY A WEAK DISTURBANCE IN THE FLOW MOVING ACROSS SOUTHERN SASKATCHEWAN ALONG THE NORTHERN PERIPHERY OF THE RIDGE. LOWER ATMOSPHERE RATHER DRY AT THIS TIME SO NOT EXPECTING ANY PRECIPITATION WITH THIS FEATURE. MODELS NOW ARE NOT REALLY ALLOWING FOR A COLD FRONT BEING PUSHED SOUTHEAST TOWARD THE AREA FROM EASTERN SASKATCHEWAN/WESTERN MANITOBA TO MAKE MUCH PROGRESS INTO THE NORTHEAST CORNER. INSTEAD THEY HAVE THE DISTURBANCE MOVING A BIT FASTER AND PUSHING IT EAST BEFORE IT REALLY MAKES MUCH INROADS INTO NORTHEAST MONTANA. MORE WEAK UPPER RIDGING FOR FRIDAY WITH A SURFACE TROF MOVING IN. NEXT SATURDAY LOOKS LIKE ZONAL FLOW AS ANOTHER WEAK DISTURBANCE MOVES ACROSS SOUTHERN CANADA AND DAMPENS THE WEAK RIDGING WHILE A TROF CARVES SOUTH IN THE EASTERN PACIFIC FROM AN UPPER LOW IN THE GULF OF ALASKA. GFS AND ECMWF ARE IN PRETTY GOOD AGREEMENT THRU SATURDAY THEN BEGIN TO DIFFER ON THE AFOREMENTIONED EASTERN PACIFIC TROF WITH THE ECMWF A BIT WEAKER WITH THE GULF OF ALASKA LOW AND MUCH WEAKER AND A BIT SLOWER WITH THE ADVANCE OF THE TROF TOWARD THE WEST COAST. THUS WHILE UPPER FLOW SHOULD BEGIN TO BACK FOR NEXT SUNDAY...HOW MUCH IS A BIG QUESTION. SO NEXT SUNDAY AND MONDAY REMAIN A FAIRLY LARGE QUESTION AS IT COULD REMAIN DRY AND STILL LEAN TOWARD THE MILD SIDE...OR IT COULD COOL OFF AND PRECIPITATE. SO FOR NOW WILL MAKE VERY FEW CHANGES OVERALL TO THE EXTENDED AND KEEP THINGS DRY...THO WILL TREND POPS NEXT SUNDAY AND MONDAY TO SLIGHTLY ABOVE CLIMATOLOGICAL NORMS INTO THE LOWER TEENS. TEMPERATURES TO REMAIN ABOVE NORMAL THRU MOST OF THE EXTENDED PERIOD...ALTHO A FEW SITES COULD DIP BELOW NORMS FOR LOWS A NIGHT OR TWO. && .AVIATION... VFR CONDITIONS ARE EXPECTED THROUGH TUESDAY. THE WIND WILL HANDS DOWN BE THE MAJOR CONCERN THE NEXT 24 HOURS. A STRONG COLD FRONT WILL CROSS THE AREA LATE TONIGHT AND EARLY TUESDAY MORNING. IN THE WAKE OF THE FRONT A W/NW WIND WILL RAPIDLY INCREASE TO 25 TO 35 KTS WITH GUSTS APPROACHING 50 KTS IN SPOTS. THE WIND WILL BEGIN TO SETTLE DOWN A BIT TOMORROW NIGHT AND WEDNESDAY...BUT WILL STILL BLOW AT A GOOD 15 TO 30 KTS WITH SOME STRONGER GUSTS ESPECIALLY AT THE EASTERN TERMINALS. CB && .FIRE WEATHER... DOWNSLOPING WINDS HAVE MADE FOR A VERY DRY AIRMASS ACROSS THE CENTRAL PART OF THE STATE...WITH DEWPOINTS IN THE SINGLE DIGITS TO LOWER TEENS. THIS DRY AIRMASS WHEN COMBINED WITH STRONG WEST TO SOUTHWEST WINDS HAS THE POTENTIAL TO MAKE FOR CRITICAL FIRE WEATHER CONDITIONS INTO TUESDAY AFTERNOON...ESPECIALLY ACROSS ZONES 119 AND 121 TONIGHT.
