AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MARQUETTE MI 404 PM EDT FRI AUG 4 2006 .DISCUSSION... CURRENTLY...LATEST WV IMGRY/RUC ANYSIS SHOWS WEAK UPPER LEVEL RIDGE OVER CENTRAL CONUS WITH SFC REFLECTION OVER UPPER GREAT LKS...AS WELL AS DEVELOPING LOW PRESSURE OVER WESTERN NORTHERN PLAIN STATES. THIS LOW WILL BE THE MAIN DISTURBANCE AFFECTING THE FORECAST OVER THE NEXT FEW DAYS. SHORT TERM...TONIGHT THRU EARLY SAT AFTN...MAIN CONCERN IS THE CHANCE FOR SHOWERS AND THUNDERSTORMS. LATEST GUIDANCE...NAM/GFS/RUC SUGGEST BEST CHANCES FOR DEVELOPMENT WILL BE ACROSS THE WEST AND NORTH...WEST OF A LINE FROM SHOT POINT TO IMT. THIS AREA CORRESPONDS TO THE BEST MID LEVEL MOISTURE AS WELL AS INSTABILITY...850-500 DTHTA/DZ. COULDNT RULE OUT PRECIP. FOR KSAW...SO USED A PROB 30 GROUP TO HIGHLIGHT LESSER CHANCE THAN KCMX. FOR TOMORROW AFTN...MAIN CONCERN WILL BE DWPT/RHS ACROSS WEST AND NORTH. CURRENT GRIDS HAVE RHS IN THE MID 30S...A BIT HIGHER ACROSS THE KEWEENAW. WITH INCREASING SOUTHERLY FLOW AHEAD OF SUNDAYS S/W AND TEMPS IN THE MID TO UPR 80S...FIRE WX ISSUES ARENT OUT OF THE QUESTION. DESPITE RECENT RAINFALL ACROSS THE U.P. AREAS OF SOUTHERN HOUGHTON COUNTY...PIEM4...REMAIN IN HIGH FIRE RISK...SEE MICFFDRS FIRE DANGER FCST FOR SPECIFICS. LONG TERM...SAT AFTERNOON AND ON...SHOWER AND THUNDERSTORM ACTIVITY SHOULD INCREASE THROUGH THE LATE SAT AFTERNOON AND EVENING HOURS AS THETA-E RIDGE AND LOW SHOWALTER AXIS APPROACH THE WESTERN CWA. EXPECT THE BEST COVERAGE/INTENSITY TO OCCUR SAT NIGHT FOR THE WESTERN PORTIONS OF THE CWA...AND LINGER INTO SUN MORNING FOR THE CENTRAL AND EASTERN CWA. WOULD EXPECT THE MAIN FOCUS OF CONVECTION TO OCCUR ALONG THE NARROW INSTABILITY AXIS WHERE MUCAPE VALUES RISE TO 1000 TO 1500 J/KG...THOUGH STORM INTENSITY AND QPF MIGHT NOT AMOUNT TO MUCH GIVEN THE WRONG TIME OF DAY...SHOULD MOISTURE ADVECTION NOT PAN OUT...AND IF THE SYSTEM WRAPS UP TOO MUCH. SPC DAY TWO OUTLOOK SHOWS BEST CHANCE FOR SEVERE WEATHER TO STAY TO THE WEST...BUT WOULD NOT RULE OUT AN ISOLATED SEVERE STORM LATE SAT NIGHT INTO EARLY SUN...ESPECIALLY SUN MORNING FOR THE SOUTH-CENTRAL AND EASTERN CWA GIVEN THE INSTABILITY PRESENT...POSSIBLE DIURNAL EFFECTS...AND THE STRONG MID-LEVEL WINDS DEPICTED SUN MORNING. MODELS INDICATE A DRYING TREND BEHIND THE FRONT SUN AFTERNOON WITH A DECENT WESTERLY FLOW DEVELOPING FOR THE AFTERNOON AND EVENING HOURS. THIS CREATES SOME CONCERN FOR DOWNSLOPE AREAS FAVORED BY WEST WINDS AS THE MAIN COLD AIR ADVECTION DOES NOT ARRIVE UNTIL SUN NIGHT...AND POST-FRONTAL WINDS LOOK TO BE FAIRLY GUSTY SUN AFTERNOON SO MIXING WOULD BE IDEAL. HAVE INCREASED HIGH TEMPS ON SUN FOR THESE AREAS A FEW DEGREES INTO THE MID 80S...BUT LATER FCSTS MAY HAVE TO WATCH FOR UPPER 80S...ESPECIALLY ALONG THE GREEN BAY SHORELINE. HIGH PRES BUILDS INTO THE UPPER MIDWEST AND UPPER GREAT LAKES FOR MON AND MON NIGHT...THEN LINGERS THROUGH THE MID WEEK. ONLY WEATHER CONCERNS FOR EARLY NEXT WEEK WOULD BE TEMPS...AS LIGHT PRES GRADIENT MAY ALLOW FOR WEAK LAKE BREEZES DURING THE AFTERNOON...AND GOOD RADIATIONAL COOLING AT NIGHT. HAVE NOT CHANGED MUCH OF THE FCST HERE OTHER THAN LOWER THE OVERNIGHT LOWS A FEW DEGREES...ESPECIALLY MON NIGHT WHEN THE SURFACE HIGH BECOMES MORE CENTERED OVER THE CWA. IN THE EXTENDED...QUIET WEATHER LOOKS TO BE THE RULE FOR MOST OF NEXT WEEK AS SURFACE HIGH PRES BUILDS OVER THE UPPER GREAT LAKES FOR MON AND TUE...AND REMAIN OVER THE REGION THROUGH WED BEFORE SLIDING SOUTHEAST AS LOW PRES ONCE AGAIN DEVELOPS OVER THE PLAINS. NOT MUCH COOLING IS EXPECTED WITH THE HIGH DURING THE DAY...SO MAX TEMPS LOOK TO REMAIN IN THE UPPER 70S TO LOWER 80S FOR THE MOST PART...WITH A GRADUAL WARMING TREND THROUGH THE WEEK. NEXT CHANCE FOR SHOWERS AND THUNDERSTORMS IS LATE IN THE WEEK WHEN MODELS INDICATE A SHORTWAVE MOVING THROUGH THE REGION...THOUGH THERE ARE SIGNIFICANT DIFFERENCES IN THE TIMING OF THIS SYSTEM. FOLLOWING A GENERAL CONSENSUS AND PER HPC GUIDANCE...HAVE WENT WITH LOW CHANCE POPS FOR THU AFTERNOON INTO FRI GIVEN THE UNCERTAINTY...AND THE WEAK FRONTAL PASSAGE DEPICTED/EXPECTED. && .MQT WATCHES/WARNINGS/ADVISORIES...NONE && SHORT TERM...PEARSON LONG TERM...LAROSA
