Area forecast discussion, Jun 4, 3:57 PM EDT, 14 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND RAPIDS MI 357 PM EDT MON JUN 4 2007 .SHORT TERM ... CONVECTION THIS EVENING WILL WEAKEN AS THE SUN SETS AND THE DEEPER COLD AIR ARRIVES. I EXPECT THE AREA OF SHOWERS OVER WISCONSIN AND WESTERN LAKE MICHIGAN TO OVERSPREAD THE CWA EARLY TONIGHT BUT JUST AS QUICKLY DEPART AS THE MUCH DRIER AIR BEHIND THE POLAR FRONT RACES IN AFTER MIDNIGHT. THAT WILL BRING PARTIAL CLEARING TOWARD MORNING. A SHORTWAVE IN THE NORTHERN STREAM WILL BRING SOME CLOUDS TUESDAY AFTERNOON INTO TUESDAY EVENING. THE MID LEVELS REMAIN RATHER DRY SO I DO NOT EXPECT ANY PCPN FROM IT HOWEVER. I KEPT A SLIGHT CHANCE OVER THE SW TO MATCH IWX GRIDS BETTER. THE NAM IS QUITE CHILLY ON TUESDAY WITH LOW LEVEL THICKNESS FIELDS SUGGESTING HIGHS NEAR 60F. THAT SEEMS HARD TO BELIEVE SO I WENT CLOSER TO THE FWC VALUES. WEDNESDAY MORNING COULD BE CHILLY SINCE THE LATEST GUIDANCE IS FASTER WITH THAT NORTHERN STREAM WAVE. SKIES COULD CLEAR ENOUGH TO ALLOW TEMPERATURES TO REACH THE UPPER 30S OVER NRN AREAS. WARM FRONT APPROACHES WEDNESDAY NIGHT. THE BEST PUSH OF MOISTURE AND THE LLJ IS NORTH OF THE GRR CWA... I PUT THE NRN SECTIONS IN FOR A CHC OF THUNDERSTORMS AFTER MIDNIGHT. THAT WILL HAVE TO BE WATCHED. .LONG TERM... THE MAIN CHALLENGE OVER THE LONG TERM DEALS WITH THE STRENGTH AND COVERAGE OF ANY THUNDERSTORMS THURSDAY INTO THURSDAY NIGHT. THE MODELS DID INITIALIZE TOO WEAK WITH THE UPPER JET OVER THE PACIFIC...SO MODEL TRENDS SHOULD BE WATCHED CLOSELY. THE MAIN CHANGES THAT I MADE TO THE FORECAST WERE FOR WARMER TEMPERATURES ON THURSDAY AND HIGHER POPS THURSDAY NIGHT. THIS UPPER JET TRACKS INTO THE PLAINS STATES FOR THE MIDDLE PART OF THE WEEK. UNSEASONABLY DEEP SURFACE LOW IS SHOWN BY THE MODELS TO INTENSIFY AND TRACK EAST NORTHEAST THROUGH THE UPPER PLAINS THURSDAY. THIS SYSTEM WILL LIFT A SURFACE WARM FRONT THROUGH SOUTHWEST LOWER MI DURING THE DAY. AN IMPRESSIVE 850 MB THERMAL RIDGE ARRIVES ALONG WITH A LLJ. MIXING TO 850 MB SUPPORTS TEMPERATURES WELL INTO THE 80S. HOWEVER MOISTURE IS LACKING ON THU...WHICH SUGGESTS THE DAY MAY BE DRY. BETTER MOISTURE ARRIVES THU EVENING...WHICH IS WHEN THE BEST CHANCE FOR RAIN WILL BE. AGAIN...THE MODELS DID NOT INITIALIZE TOO WELL WITH THIS SYSTEM IN THE PACIFIC...SO CHANGES IN TIMING AND STRENGTH ARE LIKELY. WILL MAINTAIN DRY WEATHER FOR THE WEEKEND AS HIGH PRESSURE RIDGES IN. && .GRR WATCHES/WARNINGS/ADVISORIES... MI...NONE. LM...SMALL CRAFT ADVISORY UNTIL 2 PM EDT TUESDAY FOR LMZ844>849. && SHORT TERM...WDM LONG TERM....MJS
