NWS Grand Rapids, MI wrote its last area forecast discussion before the first event at Apr 6, 10:50 PM EST, 1 hour earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND RAPIDS MI 1150 PM EDT TUE APR 6 2010 LATEST UPDATE...SHORT TERM AND MARINE... .SYNOPSIS...(504 PM EDT TUE APR 6 2010) A FRONT WILL REMAIN NEARLY STATIONARY ACROSS THE REGION THROUGH TOMORROW AND THEN MOVE SOUTHEAST AS A COLD FRONT WEDNESDAY NIGHT. SEVERAL AREAS OF SHOWERS AND THUNDERSTORMS WILL MOVE ALONG THE FRONT THROUGH WEDNESDAY EVENING. SOME OF THESE THUNDERSTORMS COULD PRODUCE DAMAGING WINDS AND LARGE HAIL. HIGH PRESSURE WILL BUILD OVER THE REGION ON FRIDAY AND BRING DRY WEATHER FOR THE WEEKEND. && .SHORT TERM...(1150 PM EDT TUE APR 5 2010) (TONIGHT THROUGH THURSDAY NIGHT) POPS WERE LOWERED FOR THE SOUTHERN HALF OF THE CWA THROUGH 06Z GIVEN RADAR TRENDS...AND THIS WILL LIKELY BE EXTENDED FURTHER AS THE WARM FRONT IS CURRENTLY OVER THE I-96 REGION. CONVECTION LOOKS TO BE IMPACTING OUR NW COUNTIES FOR THE NEXT FEW HOURS. PREVIOUS DISCUSSION FOLLOWS... EXPECT NEXT ROUND OF THUNDERSTORMS OVERNIGHT TONIGHT AS LOW LEVEL JET INCREASES AND NEXT WAVE MOVES THROUGH. FRONTAL POSITION HAS LIFTED GRADUALLY NORTH TODAY WHICH SHOULD RESULT IN A DISPLACEMENT OF THE SEVERE WEATHER THREAT NORTHWARD. SIMILAR THREATS AS LAST NIGHT WITH HAIL NORTH OF THE FRONT AND WINDS/HAIL AND SLIGHT TOR THREAT ALONG THE FRONTAL BOUNDARY. MAIN UPPER WAVE MOVES IN TOMORROW AFTERNOON WITH SEVERE RISK SHIFTING SOUTH ALONG I-94 AND TROWAL INDUCED RAIN OVER THE NE PART OF THE CWA. WRAP AROUND MOISTURE CONTINUES INTO THU WITH RW AND H85 TEMPS DROPPING TO AROUND -5C...AS SUCH TEMPS PROBABLY STRUGGLE INTO THE MID 40S MOST PLACES ON THU. QPF WISE...LOOKING FOR ANOTHER 1.00 TO 1.50 INCHES OVER THE AREA WITH LOCAL AMOUNTS OF OVER 2.00 INCHES. AREAL FLOOD ADVISORY IS A POSSIBILITY AND MOST LIKELY ALONG I-96/I-196 NEXT 24 HOURS. && .LONG TERM...(504 PM EDT MON APR 5 2010) (FRIDAY THROUGH TUESDAY) COOLER AIR WILL BE DRAGGED INTO THE REGION AS NORTHWEST FLOW TAKES OVER ON FRIDAY. MOSTLY CLEAR SKIES COULD RESULT IN A FROST OR FREEZE FRIDAY NIGHT/SATURDAY MORNING ACROSS MUCH OF THE CWA. HIGH PRESSURE OVER THE SE U.S. WILL HELP TO KEEP US DRY WITH A WARMING TREND THROUGH THE WEEKEND. ON THE BACKSIDE OF THE HIGH WE MAY SEE SOME LIGHT PCPN IN A WARM ADVECTION PATTERN SUNDAY NIGHT INTO MONDAY NIGHT. HOWEVER...OVERALL THIS APPEARS MINIMAL. A RATHER HEALTHY RETURN FLOW SHOULD BOOST TEMPS INTO THE UPPER 60S TO AROUND 70 BY TUESDAY. && .AVIATION...(1145 PM EDT TUE APR 6 2010) THE FRONT AS STALLED FROM JUST SOUTH OF MKG TO NEAR LAN AND IS WAITING FOR A SHORTWAVE SEEN OVER WI ON THE LATEST WATER VAPOR IMAGE LOOPS. ONCE THAT SHORTWAVE MOVES EAST OF THE AREA AROUND 3 AM... THE FRONT SHOULD START SAGGING SOUTHEAST AND THAT WILL SPREAD THE SHOWERS AND FINALLY LOW CEILINGS SOUTHEAST WITH IT. THE CONVECTIVE POTENTIAL IS STILL THERE FOR THE NW TAF SITES OF GRR AND MKG TONIGHT AS THE 00Z RUC SHOWS THE MOST UNSTABLE CAPE INCREASING TO NEAR 400 J/KG BETWEEN 3 AM AND 8 AM WEDNESDAY MORNING. ALSO THE TIMING TOOL BRINGS THE CONVECTIVE LINE OVER WI TO MKG BY 2 AM AND TO GRR BY 03 AM. I USED THAT IN THE TAFS AS A TEMPO GROUP. ONCE THE FRONT COMES THROUGH CEILINGS WILL BECOME IFR AND AS THE SURFACE SYSTEM AND UPPER AIR CLOSED LOW CONTINUE TO DEVELOP WRAP AROUND RAIN WILL DEVELOP AND BRING THE VSBY DOWN TO IFR TOO BY WEDNESDAY AFTERNOON. && .MARINE...(1150 PM EDT TUE APR 6 2010) FOG WAS ADDED TO THE NSH PARTICULARLY FOR THE SOUTHERN MARINE ZONES. ACROSS THESE AREAS...FOG WILL LIKELY LINGER INTO THE MID MORNING HOURS. SHOWERS AND STORMS WILL POSE A THREAT TO MARINERS THROUGH WEDNESDAY. A SMALL CRAFT ADVISORY MAY BE NEEDED WEDNESDAY NIGHT AS WAVES BUILD 3 TO 5 FEET. && .HYDROLOGY...(504 PM EDT TUE APR 6 2010) SIGNIFICANT RISES IN SMALL STREAMS AND CREEKS OCCURRED UNDER THE HEAVIEST PRECIPITATION IN OTTAWA...KENT...AND MONTCALM COUNTIES. MANY OF THE SMALLER STREAMS AND CREEKS WERE BEGINNING TO EXCEED THEIR BANKS AND OVERFLOW ONTO THE ADJACENT LOW LYING AREAS. THESE SMALLER STREAMS AND CREEKS WILL REACH THEIR CREST IN THE NEXT 12 TO 18 HOURS. RISES ON THE LARGER RIVERS ARE EXPECTED OVER THE NEXT COUPLE DAYS...AS SIGNIFICANT RAINFALL ON THE ORDER OF 1 TO 2 INCHES HAS OCCURRED OVER THE AREA...AND IT IS ANTICIPATED THAT ANOTHER INCH OF RAINFALL IS POSSIBLE OVER THE NEXT 24 HOURS. RIVER FLOOD ADVISORIES WERE ISSUED FOR MULTIPLE LOCATIONS IN THE GRAND RIVER BASIN AND ANY ADDITIONAL RAINFALL WILL PUSH RIVER LEVELS UP CLOSER TO FLOOD STAGE. ANY ADDITIONAL RAINFALL...OVER THE AREAS THAT HAVE ALREADY RECEIVED 1 TO 2 INCHES OF RAINFALL OVER THE PAST 24 HOURS... COULD LEAD TO WIDESPREAD AREAL FLOODING. && .FIRE WEATHER...(504 PM EDT TUE APR 6 2010) GIVEN THE EXPECTED RAINFALL...LITTLE IF ANY FIRE WEATHER THREAT IS PRESENT FOR THE ENTIRE GRR CWA. CONDITIONS WILL NOT DRY OUT UNTIL THURSDAY. && .GRR WATCHES/WARNINGS/ADVISORIES... MI....NONE.
