AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MARQUETTE MI
753 AM EDT MON JUN 23 2014
.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 522 AM EDT MON JUN 23 2014
WV IMAGERY AND RUC ANALYSIS INDICATED WSW FLOW INTO THE NRN LAKES
BETWEEN A MID/UPPER LEVEL TROUGH FROM MANITOBA INTO THE NRN PLAINS
AND A RIDGE FROM THE OHIO VALLEY INTO QUEBEC. AT THE SFC...A WEAK
TROUGH EXTENDED FROM NE MN INTO WRN WI. A MORE PROMINENT COLD FRONT
STRETCHED FROM JAMES BAY TO NEAR WINNIPEG AHEAD OF HIGH PRESSURE
OVER N CNTRL CANADA. FORCING FROM A WEAK SHRTWV IN NRN WI ALONG WITH
AN AXIS OF HIGHER MOISTURE WITH PWAT VALUES TO 1.4 INCHES...WAS
ENOUGH TO SUPPORT AN AREA OF SHOWERS OVER FROM SW UPPER MI INTO E
CNTRL WI.
TODAY...EXPECT THE SHRTWV AND AREA OF PCPN ONLY SLOWLY MOVE TO THE
EAST THIS MORNING. WITH ONLY WEAK LARGE SCALE FORCING EXPECTED INTO
THE AFTERNOON AND THE POTENTIAL FOR ANOTHER WEAK SHRTWV TO MOVE INTO
THE AREA DURING INCREASED DAYTIME HEATING...THE FCST KEEPS MENTION
OF JUST SCT SHRA WITH THE GREATEST COVERAGE EXPECTED OVER CNTRL
UPPER MI. WITH TEMPS CLIMBING INTO THE MID 70S...THERE MAY BE ENOUGH
INSTABILITY FOR SOME ISOLD/SCT TSRA AS MLCAPE VALUES CLIMB INTO THE
400-800 J/KG RANGE.
TONIGHT...WITH THE LOSS OF DAYTIME HEATING...THE PCPN COVERAGE
SHOULD DIMINISH. HOWEVER...INCREASED QVECTOR CONV AHEAD OF THE MID
LEVEL TROUGH MOVING INTO THE UPPER MS VALLEY WILL SUPPORT CONTINUED
CHANCES FOR SCT SHOWERS AND A FEW TSRA.
.LONG TERM...(TUESDAY THROUGH SUNDAY)
ISSUED AT 421 AM EDT MON JUN 23 2014
ON TUESDAY MORNING...THE MODELS ARE IN GOOD AGREEMENT IN SHOWING THE
COLD FRONT MOVING OVER OR JUST SOUTH OF THE AREA. HOWEVER...THE
850MB TROUGH AXIS HANGS UP OVER LAKE SUPERIOR AS THERE IS LACK OF A
SOUTHWARD PUSH DUE TO THE GENERAL ZONAL FLOW ALOFT. THIS WILL
PROVIDE THE FOCUS FOR PRECIPITATION ON TUESDAY ESPECIALLY SINCE THE
MODELS ARE IN EXCELLENT AGREEMENT IN SHOWING BROAD SYNOPTIC SUPPORT
MOVING THRU AS THE 500MB TROUGH AXIS MOVES THROUGH. AS SUCH...THERE
WILL LIKELY BE SCATTERED SHOWERS ACROSS THE ENTIRE FORECAST AREA
THROUGH THE DAY DESPITE THE SURFACE FRONT BEING SOUTH OF THE REGION.
THE NUMERICAL GUIDANCE ALSO SHOWS MUCAPE VALUES OF 500-1500 J/KG
ACROSS THE REGION DURING THE DAY WITH MID LEVEL LAPSE RATES OF 6+
C/KM...ALLOWING FOR POSSIBLE THUNDERSTORM DEVELOPMENT. BEST CHANCES
FOR THUNDER WOULD BE ACROSS THE SOUTHERN TIER WHERE SFC TEMPS WILL
LIKELY BE IN THE LOWER-MID 70S AND IS WHERE THE BEST INSTABILITY
WILL BE LOCATED. WILL NEED TO KEEP CHANCE POPS ACROSS THE EASTERN
HALF OF THE FORECAST AREA DURING THE TUE EVENING HOURS AS WELL GIVEN
REMAINING MID LEVEL FORCING AND REMAINING DAYTIME INSTABILITY.
AT THIS TIME...WEDNESDAY IS EXPECTED TO REMAIN DRY AND COOL WITH THE
850MB TROUGH AND SFC FRONT REMAINING SOUTH OF THE AREA. STILL SOME
WEAK TROUGHINESS AT 500MB AND AS SUCH WEAK MID LEVEL Q-VECTOR
CONVERGENCE AND MOISTURE PERSISTS ACROSS THE AREA ALL DAY.
HOWEVER...GIVEN LACK OF INSTABILITY AND VERY WEAK MID LEVEL LAPSE
RATES COMBINED WITH ANTICYCLONIC LOW LEVELS WILL KEEP IT DRY FOR
NOW. WOULD NOT BE SHOCKED TO SEE ISOLATED SHOWERS BUT CHANCES ARE
NOT HIGH ENOUGH TO INCLUDE IN THE FORECAST AT TIME TIME.
IN THE EXTENDED...ZONAL FLOW THROUGH THE PERIOD WILL MAKE TIMING OF
PRECIPITATION SOMEWHAT DIFFICULT ESPECIALLY INTO THE WEEKEND.
HOWEVER...THE LONGER RANGE MODELS ARE IN DECENT AGREEMENT ON THE
BROAD SCALE FEATURES WHICH AT LEAST GIVES SOME BASIC CONFIDENCE ON
WHEN THE BETTER CHANCES FOR RAIN WILL BE. ON THURSDAY...THE ECMWF
AND GFS BOTH SHOW A COMPACT VORT MAX MOVING ACROSS THE AREA DURING
THE DAY AS THE 850MB FRONT MOVES BACK NORTH. ALTHOUGH MOISTURE WILL
BE VERY LIMITED...WILL INCLUDE CHANCE POPS FOR THE WESTERN HALF OF
THE FORECAST AREA. BEHIND THIS VORT MAX...UPPER RIDGING BUILDS
ACROSS THE AREA FOR FRIDAY WHICH SHOULD ALLOW FOR TEMPS TO RETURN TO
NORMAL AS WELL AS DRY WEATHER. RETURN FLOW BEGINS IN EARNEST FOR THE
WEEKEND WITH TEMPERATURES LIKELY TO RISE ABOVE NORMAL...AND PERHAPS
A LITTLE MORE HUMIDITY AND SUMMER LIKE WEATHER. THIS WILL ALLOW FOR
CHANCES OF SHOWERS AND STORMS EACH DAY...ALTHOUGH SUNDAY LOOKS LIKE
THE BETTER CHANCE FOR SHOWERS AND STORMS GIVEN LOWERING HEIGHTS
ACROSS THE AREA IN RESPONSE TO THE APPROACHING TROUGH.

BRING SCT SHRA TODAY INTO THIS EVENING. HOWEVER...MAINLY VFR CONDITIONS ARE
EXPECTED AS MOST OF THE RAIN WILL BE LIGHT. ISOLATED THUNDERSTORMS
ARE ALSO POSSIBLE...MAINLY THIS AFTERNOON AND EVENING. HOWEVER...THE
PROBABILITY IS LOW ENOUGH TO LEAVE OUT MENTION FROM THE TAF. WITH
