Area forecast discussion, Jun 23, 12:57 PM EST, 48 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI 157 PM EDT MON JUN 23 2008 .AVIATION... SCATTERED SHOWERS AND THUNDERSTORMS WILL FILL IN ACROSS SOUTHEAST MICHIGAN THROUGH THE AFTERNOON AS AN UPPER LEVEL SHORTWAVE SWINGS SOUTH ACROSS THE AREA. A FEW OF THE STRONGER THUNDERSTORMS MAY PRODUCE BRIEF HEAVY RAIN AND SMALL HAIL AND WILL ADJUST THUNDERSTORM TIMING AS STORMS DEVELOP THIS AFTERNOON AND CONFIDENCE IN IMPACTING THE TAF SITES INCREASES. CEILINGS WILL GENERALLY REMAIN VFR EXCEPT IN THE HEAVIER SHOWERS. WILL EXPECT SKIES TO SCATTER OUT THIS EVENING AS DIURNAL INSTABILITY WANES. MODELS DO INDICATE SOME RESIDUAL LOW LEVEL MOISTURE ARRIVING WITH THE POSSIBILITY OF AN MVFR CLOUD DECK OVERNIGHT...BUT AT THIS TIME THINK WE WILL JUST SEE SCATTERED VFR CLOUDS UNTIL DAYTIME HEATING CONTRIBUTES TO A SCATTERED CU DECK LATE TUESDAY MORNING. && .PREV DISCUSSION...ISSUED 344 AM EDT MON JUN 23 2008 SHORT TERM...TODAY THE UPPER LOW THAT HAS BEEN IMPACTING THE STATE OVER THE WEEKEND IS NOW SITUATED OVER LAKE HURON. THIS WAVE IS FORECAST TO FILL IN AND MOVE EAST OF THE STATE TODAY. HOWEVER...SEASONALLY COLD 500MB TEMPS AROUND -18C AND LINGERING LOW LEVEL CYCLONIC FLOW WILL ONCE AGAIN AID IN THE DEVELOPMENT OF DIURNALLY ENHANCED AFTERNOON AND EVENING CONVECTION. LOW LEVEL COLD AIR ADVECTION THIS MORNING UNDER NORTH-NORTHWESTERLY FLOW WILL DROP 850MB TEMPS DOWN TO +9C BY AFTERNOON. THIS WILL CAUSE THE LOWER AND MID LEVEL LAPSE RATES TO BE NOT QUITE AS STEEP AS YESTERDAY. 0-1KM MIXED LAYER CAPE ON NAM MODEL SOUNDINGS THIS AFTERNOON ONLY RANGES FROM 400-800 J/KG. SO OVERALL...EXPECT THE COVERAGE AND INTENSITY OF AFTERNOON/EVENING THUNDERSTORMS TO BE LESS THAN YESTERDAY. AN AXIS OF HIGHER 925-850MB MOISTURE HOWEVER IS FORECAST TO DROP INTO SE MI FROM THE NORTHWEST THIS MORNING. THIS MOISTURE IS ALREADY PRESENTING ITSELF AS A RAPIDLY EXPANDING STRATUS DECK OVER LAKE MICHIGAN. THIS MOISTURE WILL LEAD TO A FAIRLY DECENT STRATO CU FIELD BY AFTERNOON. SO ALTHOUGH THE COVERAGE OF THUNDERSTORMS MAY BE MORE SCATTERED IN NATURE...DO EXPECT THE HIGHER MOISTURE IN THE LOW LEVELS TO LEAD TO A DECENT COVERAGE OF GENERAL SHOWERS THIS AFTERNOON. THE CURRENT WATER VAPOR LOOP SHOWS NUMEROUS SHORT WAVES PIVOTING AROUND THE UPPER LOW...THE STRONGEST OF WHICH IS CURRENTLY MOVING ACROSS SOUTHERN LAKE HURON. SHORT WAVE ENERGY TRAVERSING THE SOUTHERN MI BORDER MAY CONTINUE TO DRIVE SOME ISOLATED CONVECTION THIS MORNING. ADDITIONAL SHORT WAVES ARE NOTED OVER NORTHERN LAKE MI AND EASTERN UPPER MI...WHICH SHOULD ALSO ENHANCE COVERAGE OF AFTERNOON SHOWERS AS THEY DROP SOUTH ACROSS LOWER MI. MAX TEMPS WILL BE A FEW DEGREES COOLER TODAY COMPARED TO YESTERDAY DUE TO THE LOW LEVEL COLD AIR AND MOISTURE ADVECTION. THE CURRENT FORECAST HAS MAX TEMPS IN THE LOWER TO MID 70S WHICH STILL LOOKS REASONABLE. LONG TERM...TONIGHT THROUGH SUNDAY THE NARROWING UPPER LEVEL TROUGH AXIS WILL PUSH EASTWARD RATHER QUICKLY THIS EVENING PROVIDING SOUTHEASTERN MICHIGAN A MUCH DESERVED REST FROM LOWERED GEOPOTENTIAL HEIGHTS. THIS ANTICIPATED PATTERN CHANGE RESULTS FROM THE PLUNGING OF A POWERFUL KICKER WAVE ACROSS HUDSON BAY. AN EXTENDED PERIOD OF ZONAL FLOW WILL SET UP ACROSS THE NORTHERN TIER STATES WITH PRIMARY JET PLACEMENT ACROSS EXTREME SOUTHERN CANADA. THEREFORE...EXPECT TEMPERATURES FOR MUCH OF THIS WEEK TO REACH/ECLIPSE THE 80 DEGREE MARK. RISING HEIGHTS AND SURFACE HIGH PRESSURE WILL TEAM WITH DEEP DRY AIR TO GIVE PRECIPITATION FREE CONDITIONS THROUGH TUESDAY NIGHT. A WONDERFUL TUESDAY IS EXPECTED WITH AREA RESIDENTS WITNESSING ABUNDANT SUNSHINE AND TEMPERATURES IN THE THE UPPER 70S. LOWS TONIGHT AND TUESDAY NIGHT ARE EXPECT TO FALL INTO THE 50S...LOWER NORTH/UPPER SOUTH. THE THREAT OF THUNDERSTORMS RETURNS ON WEDNESDAY...ALTHOUGH TIMING/LOCATION AGREEMENT IS FAR FROM RESOLVED. ALL INDICATIONS POINT TO A CONVECTIVE COMPLEX TRACKING THROUGH THE MIDWEST LATE WEDNESDAY/WEDNESDAY NIGHT. THIS SYSTEM IS EXPECTED TO ANCHOR ITSELF ON THE LOW TO MIDLEVEL MOISTURE/THETA E GRADIENT AS IT ADVECTS EASTWARD. ALTHOUGH THE NAM IS EARLIER AND FARTHER SOUTH...THE SOUNDINGS HINT THAT ANY PRECIPITATION SHOULD WAIT UNTIL AFTER 18Z. SURFACE HIGH PRESSURE BUILDING INTO THE CAROLINAS WILL FORCE THE SOUTHWESTERLY RETURN FLOW AND THE RESULTANT SWEEPING OF STEEPER MIDLEVEL LAPSE RATES. THE PREVIOUS FORECAST HAD THIS HANDLED WELL WITH A CHANCE OF SHOWERS AND THUNDERSTORMS. WILL MAINTAIN THE DRY FORECAST FOR THURSDAY...AS A SHORTWAVE RIDGE AXIS TRANSLATES THROUGH THE STATE (ESPECIALLY IN THE ECMWF). THE EXTREMELY BUSY ZONAL FLOW BRING SHOWERS AND THUNDERSTORMS BACK IN THE FORECAST TO CAP OFF THE WORK WEEK. THE GFS IS AGAIN TRACKING DEVELOPED SURFACE REFLECTIONS THROUGH THE STATE IN QUICK SUCCESSION...BUT CONFIDENCE IS SEVERELY LACKING WITH EACH AND EVERY ONE OF THESE. THIS COULD PROVE TO BE A BUSY PERIOD AS THE FORECAST AREA WILL LIE ALONG THE EDGE OF THE RIDGE AND MIDLEVEL CAPPING. HOWEVER...THE LOCATION OF THERMAL GRADIENTS AND OVERALL STORM SCALE DYNAMICS WILL DICTATE THE COVERAGE/ACTIVITY. MARINE... RELATIVELY LIGHT WINDS WILL PERSIST TODAY THROUGH TUESDAY AS HIGH PRESSURE BUILDS IN FROM THE WEST. THIS HIGH WILL TRIGGER NORTH-NORTHEASTERLY WINDS ACROSS LAKE HURON AND SAGINAW BAY TODAY. SPEEDS WILL STILL HOWEVER BE 10 KNOTS OR LESS. && .DTX WATCHES/WARNINGS/ADVISORIES... MI...NONE. LAKE HURON...NONE. LAKE ST CLAIR...NONE.
