Area forecast discussion, Jul 25, 11:35 AM CST, 1 hour 30 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DULUTH MN 1235 PM CDT THU JUL 25 2013 .AVIATION.../18Z TAF ISSUANCE/ SCATTERED SHOWERS AND THUNDERSTORMS ACROSS NE MINNESOTA AND NW WISCONSIN THIS AFTERNOON AS A LOW PRESSURE SYSTEM AND ITS COLD FRONT APPROACH AND BEGIN TO MOVE THROUGH THE REGION. STORMS ARE MOSTLY LIKELY TO BEGIN TO AFFECT THE KINL AND KBRD AREAS EARLY THIS AFTERNOON...AND THEN THE KHIB/KDLH/KHYR MID TO LATE THIS AFTERNOON. MVFR CIGS AT KINL WILL LIKELY CONTINUE THROUGH THIS AFTERNOON...BUT THE KBRD/KHIB/KDLH/KHYR SHOULD LIKELY CONTINUE TO SEE VFR CONDITIONS. THERE MAY BE BRIEF MVFR CIGS/VSBYS IF ANY SHOWERS/STORMS DIRECTLY HIT ANY TERMINALS. THE STORMS SHOULD WIND DOWN EARLY THIS EVENING. THE COLD FRONT WILL MOVE THROUGH THE REGION LATE THIS AFTERNOON AND THIS EVENING. THE FRONT WILL USHER IFR/MVFR CIGS AND RAIN SHOWERS OUT OF CANADA INTO THE REGION LATE THIS EVENING INTO EARLY FRIDAY MORNING. THERE MAY EVEN BE LIFR CIGS. FOG IS POSSIBLY LATE TONIGHT AT KDLH AND KHYR...WITH KHYR HAVING THE BEST CHANCE. THERE SHOULD BE SOME LIFTING OF THE CIGS LATER FRIDAY MORNING WITH IFR/MVFR CIGS CONTINUING ACROSS THE REGION WITH SHOWERS. THE LIGHT SW TO WNW WINDS EARLY THIS AFTERNOON WILL BEGIN TO BECOME W TO NW LATER THIS AFTERNOON AS THE FRONT BEGINS TO MOVE INTO NE MINNESOTA. THE WINDS SHOULD WEAKEN THIS EVENING...THEN INCREASE AND BECOME WNW TO NNW LATE TONIGHT AND FRIDAY MORNING. && .PREV DISCUSSION... /ISSUED 1033 AM CDT THU JUL 25 2013/ UPDATE... WE'VE UPDATED THE SHORT TERM GRIDS TO ACCOUNT FOR THE LACK OF SHOWERS/STORMS THIS MORNING. WE DID SEE SOME SHOWERS DEVELOP OVER PRICE/IRON/ASHLAND/SAWYER COUNTIES BUT THESE WERE NOW MOVING EAST. MORE SHOWERS/STORMS WERE MOVING SOUTHEAST TOWARD KOOCHICHING COUNTY AND WILL AFFECT THAT AREAS WITHIN THE HOUR. OVERALL...WE DO EXPECT SCATTERED TO NUMEROUS SHOWERS/STORMS TO DEVELOP AS THE DAY PROGRESSES AND WE GET SOME HEATING. SOME OF THE HIGH CAMS SHOW STRONGEST STORMS DEVELOPING SOUTH AND EAST OF THE NORTHLAND...WHICH WOULD AGREE WITH THE LATEST SWODY1. HOWEVER...THE NORTHLAND COULD STILL SEE SOME STRONG STORMS YET THIS AFTERNOON AND EARLY EVENING. SKIES WERE CLEAR TO PARTLY CLOUDY OVER A GOOD PART OF NORTHWEST WISCONSIN BACK INTO THE TWIN PORTS...BRAINERD LAKES...LONGVILLE AND WALKER AREAS. CLOUDS SHOULD FILL IN THROUGH THE DAY THOUGH. SIGNIFICANTLY COLDER AIR WILL BE MOVING IN TONIGHT...LASTING THROUGH THE WEEKEND. PREV DISCUSSION... /ISSUED 339 AM CDT THU JUL 25 2013/ LONG TERM....FRIDAY THROUGH WEDNESDAY. MAIN FOCUS IN LONG TERM ON TEMPS AND SHRA CHANCES AS A COLD CORE CLOSED LOW SETTLES OVER WESTERN LAKE SUPERIOR THROUGH THE WEEKEND. HAVE CONTINUED DOWNWARD TREND TO TEMPS/DEW POINTS FRIDAY THROUGH SUNDAY AS THE NORTHLAND BECOMES POSITIONED IN THE WRAP AROUND CAA ON THE BACK SIDE OF THE LOW. THE NAM/ECM/GFS HAVE SHOWN RUN TO RUN CONSISTENCY AND AGREEMENT THAT A CORRIDOR OF H85 TEMPS AROUND 3-5 C...AND H50 TEMPS AROUND NEGATIVE 20 C...DIVES INTO THE BORDERLAND/ARROWHEAD ZONES THROUGH THE DAY FRIDAY...ANCHORING OVER WESTERN LAKE SUPERIOR THROUGH AT LEAST SUNDAY MORNING. THE COLD AIR ALOFT WILL RESULT IN VERY STEEP LAPSE RATES AND ANY SUN/DAYTIME HEATING WILL LEAD TO GUSTY NORTH WINDS AND INSTABILITY/LAKE ENHANCED SHOWERS. HAVE INCREASED CLOUD COVER AND KEPT SMALL POPS FRIDAY/SATURDAY FOR MOST AREAS AS ANY LINGERING MOISTURE WILL SUPPORT ISOLD/SCT SHRA. AT THIS TIME CAPE VALUES ARE ON THE ORDER OF 100-200 J/KG SO HAVE LEFT OUT MENTION OF THUNDER THIS WEEKEND. DIFFICULTLY REMAINS IN TIMING THE DEPARTURE OF THE LOW...WHICH WILL BECOME REPLACED BY A SFC RIDGE AND MUCH DRIER AIR. THE LATEST ECM RUN HAS TRENDED TOWARDS THE GFS SOLUTION FOR A SLOWER EXIT OF THE COLD AIR/CLOUDS. IF THIS TREND CONTINUES...THE CLOUD COVER AND SHOWERS MAY NEED TO BE PUSHED FURTHER WEST SAT/SUN. THERE IS REASONABLE AGREEMENT IN LONG TERM MODELS THAT THE RIDGE AXIS MAKES IT INTO AT LEAST NORTH CENTRAL MINN SAT NIGHT. THE COMBINATION OF STRONG MIXING SATURDAY AFTERNOON TO BRING VERY LOW DEW POINTS...AND CLEAR SKIES/LIGHT WINDS SATURDAY NIGHT WILL BRING THE POTENTIAL FOR WIDESPREAD OVERNIGHT TEMPERATURES IN THE 30S TO LOW 40S ACROSS MUCH OF NORTH-CENTRAL/NORTHEAST MINNESOTA. ANOTHER SHORT WAVE IS EXPECTED TO TRACK OVER THE REGION AND BRING A CHANCE FOR SHOWERS AND THUNDERSTORMS DURING THE MONDAY NIGHT THROUGH TUESDAY NIGHT TIME FRAME. && .POINT TEMPS/POPS...
