NWS Glasgow, MT wrote its last area forecast discussion before the first event at Jun 21, 2:07 AM MST, 53 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GLASGOW MT 307 AM MDT TUE JUN 21 2005 .SHORT TERM...FOR NORTHEAST MONTANA TODAY THROUGH THURSDAY... ANOTHER NIGHT...ANOTHER MCS. THE ACTIVE WEATHER PATTERN OF LATE SHOWS NO SIGNS OF SETTLING DOWN ANY TIME SOON. A LARGE SUMMERY RIDGE MORE TYPICAL OF MID-JULY THAN MID-LATE JUNE COVERS THE CENTRAL CONUS WITH 500H APPROACHING 600DM AT TIMES ACROSS THE SOUTHERN AND CENTRAL PLAINS...AND 1000-500H THICKNESS VALUES AS HIGH AS THE 580S ACROSS NORTHEAST MONTANA. THERE EVEN APPEARS TO BE SOME MONSOONAL MOISTURE GETTING INTO THE ACT AT TIMES ACROSS OLD MEXICO...AND A LITTLE MONSOONAL MOISTURE EVIDENT ACROSS THE SOUTHWEST CONUS. NORTHEAST MONTANA WILL REMAIN ON THE PERIPHERY OF THE UPPER RIDGE...AND IN A LOCATION THAT IS TYPICALLY FAVORABLE FOR ROUNDS OF SEVERE WEATHER...MOST OF WHICH LOOKS TO BE NOCTURNAL. POSSIBLE FOR ADDITIONAL MCS TO DEVELOP ACROSS THE AREA AGAIN TONIGHT. AS THE UPPER RIDGE SHIFTS A LITTLE FURTHER NORTH THE AREA MAY TEND TO REMAIN MORE CAPPED AND POSSIBLE THAT CONVECTION MAY FIRE IN CANADA AND DROP DOWN INTO THE DAKOTAS. TODAY...MCS #1 IS RACING EAST AND IS EXITING OUR EASTERN ZONES EARLY THIS MORNING. THERE SHOULD THEN BE A LULL IN THE ACTIVITY WHICH WILL ALLOW THINGS TO HEAT UP AGAIN TODAY WITH MOST OF THE CWA TOPPING OUT WELL INTO THE 90S. THE AXIS OF GREATEST INSTABILITY SHOULD LAY SQUARELY ACROSS NORTHEAST MONTANA WITH CAPE VALUES IN EXCESS OF 3000 J/KG AND LI/S DOWN AROUND -6C BY AFTERNOON...BUT THINKING THAT THERE ARE WILL LIKELY BE CAPPED AS THE UPPER RIDGE BUILDS NORTH WITH WARMER AIR ALOFT AND 700H TEMPERATURES WELL UP INTO THE TEENS (C). BUFKIT SOUNDINGS SEEM TO SUPPORT THIS IDEA WITH A CAP UP AROUND 750-800H. THE DAY SHIFT MAY WANT TO CONSIDER AN 18Z SOUNDING TO GET A BETTER PICTURE OF WHAT THINGS LOOKS LIKE AFTER SEVERAL HOURS OF HEATING. THINKING THAT ONCE THE ACTIVITY EXITS INTO NORTH DAKOTA THIS MORNING THAT THERE IS A GOOD CHANCE THAT THE REMAINDER OF THE DAY WILL BE FREE OF ANY CONVECTION. POSSIBLE THAT IF THERE IS A SLIGHTLY STRONGER SHORTWAVE IN THE FLOW THAT IT COULD BE ENOUGH TO INITIATE ISOLATED CONVECTION. TONIGHT...POSSIBILITY FOR YET ANOTHER ROUND OF SEVERE WEATHER. TOUGH CALL TO SAY JUST WHERE THINGS WILL SET UP. SOME CONVECTION LIKELY TO FIRE UP ACROSS THE HIGHER TERRAIN TO OUR WEST DURING THE DAY AND MAY DRIFT INTO OUR WESTERN ZONES DURING THE EVENING (JUST LIKE LAST NIGHT). POSSIBLE THAT ANOTHER MCS COULD TRY TO GET GOING DURING THE NIGHT GIVEN THE UPPER PATTERN WHERE WE ARE ON THE EDGE OF THE UPPER HIGH. AS THE UPPER RIDGE WILL BE FURTHER NORTH THE BEST CHANCE OF CONVECTION MAY BE A LITTLE FURTHER TO THE NORTH IN CANADA. COULD BE SIMILAR TO TONIGHT WHERE A SUPERCELL OR TWO DEVELOPS INTO AN MCS WITH A TRANSITION FROM A LARGE HAIL THREAT TO A HAIL AND STRAIGHT LINE WIND. PLAN TO MENTION THE SEVERE THREAT IN THE GRIDS. WEDNESDAY...THE UPPER RIDGE CONTINUES TO COVER THE THE CENTRAL CONUS. AN UPPER TROUGH WILL LIFT THROUGH SOUTHWEST CANADA WITH A COLD FRONT TO ORGANIZE ACROSS CENTRAL AND SOUTHWEST MONTANA DURING THE DAY. IT SHOULD HEAT UP OUT AHEAD OF THE FRONT ONCE AGAIN WITH 850H TEMPERATURES IN EXCESS OF +30C ACROSS OUR EASTERN ZONES. HIGHS SHOULD AGAIN TOP OUT WELL INTO THE 90S AND A FEW SPOTS MAY TOP 100F FOR THE FIRST TIME THIS YEAR. BUMPED UP THE TEMPERATURES A FEW DEGREES IN THE GRIDS. THE THERMAL RIDGE ACROSS THE AREA OUT AHEAD OF THE COLD FRONT SHOULD ACT TO KEEP THINGS CAPPED...BUT MAY SEE SOME ISOLATED CONVECTION DEVELOP DURING THE AFTERNOON. WED NIGHT & THURSDAY...THE COLD FRONT PUSHES EAST AND ACROSS THE AREA WEDNESDAY EVENING...AND MAY TOUCH OFF ANOTHER ROUND OF CONVECTION. IT WILL BE A GOOD 15 DEGREES COOLER BEHIND THE FRONT THURSDAY WITH 850H TEMPS TUMBLING BACK INTO THE TEENS (C). THE ATMOSPHERE SHOULD BE MUCH MORE STABLE BEHIND THE FRONT...AND OUR UPPER FLOW WILL AT LEAST TEMPORARILY BECOME MORE WESTERLY. THINK THERE IS A GOOD CHANCE THAT IT WILL BE A DRY DAY...BUT KEPT SOME LOW POPS IN...MAINLY ACROSS OUR EASTERN ZONES TO MAINTAIN GOOD COORDINATION. CB .LONG TERM...THURSDAY NIGHT THROUGH MONDAY... BUSY NIGHT WITH STORMS HAS LIMITED THE AMOUNT OF TIME SPENT ON DELVING INTO THE EXTENDED. HOWEVER...MODELS DO NOT APPEAR TO BE VEERING MUCH FROM PREVIOUS WITH SOUTHWEST FLOW ALOFT PREVAILING FOR MOST OF THE PERIOD. BREAK COULD POTENTIALLY BE FRIDAY...OR FRIDAY AND SATURDAY AFTER FRONT MOVES THRU WEDNESDAY NIGHT AND UPPER TROF THURSDAY AND FLOW ALOFT BECOMES MORE ZONAL BEFORE RETURNING TO SOUTHWESTERLY. HOWEVER...SOMETHING COULD STILL CREEP OUR WAY IN ZONAL FLOW SO FOR NOW WILL KEEP SLIGHT CHANCE POTENTIAL GOING PRETTY MUCH THROUGHOUT. TEMPERATURES WILL COOL SIGNIFICANTLY AFTER WEDNESDAYS TOASTY DAY FOR WEEKS END. EARLY NEXT WEEK COULD BE QUITE NASTY AS MODELS SHOWING ANOTHER GOOD FRONTAL PASSAGE FOLLOWED BY NICE SHORTWAVE. && AVIATION... VFR UNTIL TUESDAY EVENING WHEN STORMS MAY DROP ANY SITE TO IFR OR LIFR. && .GLASGOW WATCHES/WARNINGS/ADVISORIES...SEVERE THUNDERSTORM WATCH #508 IN EFFECT UNTIL 6 AM MDT FOR ALL ZONES. && WEATHER.GOV/GLASGOW
