CRAVENWhat forecasters said that day
The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Milwaukee, WI wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 19, 3:00 PM CDT, 11 hours 44 minutes earlier.
Area forecast discussion, Jul 19, 3:00 PM CDT, 11 hours 44 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MILWAUKEE/SULLIVAN WI 300 PM CDT WED JUL 19 2006 .DISCUSSION...FORECAST FOCUS ON SEVERE WEATHER AND HEAVY RAIN POTENTIAL TONIGHT. SEVERE MCS THAT MOVED THROUGH MINNESOTA THIS MORNING HAS WEAKENED INTO MAINLY RAIN. THIS AREA IS CURRENTLY MOVING SLOWLY EAST ACROSS THE WESTERN PORTION OF THE FORECAST AREA. MORE SEVERE STORMS FORMED TO THE SOUTH OF THIS MCS IN NORTHEAST IOWA...WHICH MOVED SOUTHEAST INTO EASTERN IOWA AND NORTHWEST ILLINOIS. MAIN FORECAST CHALLENGE IS DETERMINING IF MORE CONVECTION WILL MOVE INTO THE FORECAST AREA LATER THIS EVENING AND OVERNIGHT...AND SEVERE/HEAVY RAIN POTENTIAL. WRF MODEL HAD A REASONABLE SPATIAL DEPICTION OF THE MCS THIS MORNING...ALTHOUGH ITS TIMING WAS WAY TOO SLOW IN MOVING IT EAST AND SOUTHEAST THROUGH THE REGION. THE WRF AND THE RUC BOTH SHOW NEW CONVECTION INITIATING IN NORTHERN IOWA AROUND 00Z THURSDAY...NEAR THE SURFACE WARM FRONT AND LOW LEVEL JET NOSE INTERSECTION. THE WRF THEN DEVELOPS ANOTHER MCS...AND TAKES IT SOUTHEAST ACROSS EASTERN IOWA INTO NORTHWEST ILLINOIS BY 12Z THURSDAY...MISSING SOUTHERN WISCONSIN. IN CONTRAST...THE GFS DEVELOPS THE CONVECTION MUCH FURTHER NORTH IN MINNESOTA...TAKING IT SOUTHEAST ACROSS THE FORECAST AREA DURING THIS TIME. THE LATEST 12Z HIGH RESOLUTION WRF MODEL ALSO DEVELOPS CONVECTION OVER NORTHERN IOWA...BUT TAKES IT DUE EAST INTO THE FORECAST AREA BY 06Z THURSDAY. PREFER THE WRF/HIGH RESOLUTION WRF OVER THE GFS WITH THIS SCENARIO...AS THEY SEEMED TO HAVE A BETTER HANDLE ON SURFACE AND UPPER FEATURES...AND THE CONVECTION THIS MORNING. HOWEVER...THE USUAL MODEL PROBLEMS WITH HANDLING CONVECTION CONTINUES TO PRESENT SOME UNCERTAINTY. IF THE MCS DOES MOVE INTO THE FORECAST AREA...THE SOUTHWEST HALF OF THE FORECAST AREA WOULD PROBABLY HAVE THE BEST CHANCE. SO...WILL LOWER POPS SLIGHTLY TO THE 60 TO 70 RANGE FOR TONIGHT. SEVERE WEATHER IS STILL POSSIBLE...IN THE FORM OF A FORWARD PROPAGATING MCS AND/OR DERECHO. ELEVATED CAPES OF 2500 TO 4000 J/KG...AND 0-6KM SHEAR VALUES OF 40 TO 50 KNOTS ARE EXPECTED. THE STRONG CAPPING INVERSION IN THE LOW LEVELS...CIN VALUES OF 200 TO 250 J/KG...WILL AGAIN BE A LIMITING FACTOR. HOWEVER...IF A SEVERE MCS/DERECHO DOES FORM TO THE WEST...THE LARGE CIN WOULD NOT PREVENT IT FROM MOVING EAST THROUGH THE FORECAST AREA. PRECIPITABLE WATER VALUES OF 2.00 INCHES...SOMETIMES HIGHER...WILL ALSO MEAN THE POTENTIAL OF HEAVY RAINFALL...DESPITE THE EXPECTED PROGRESSIVE NATURE OF ANY MCS. ANY CONVECTION SHOULD MOVE OUT OF THE FORECAST AREA THURSDAY MORNING. HIGH PRESSURE RIDGE THEN MOVES INTO THE NORTHERN PLAINS FOR THURSDAY NIGHT INTO FRIDAY...BRINGING COOLER AND LESS HUMID CONDITIONS. EXTENDED RANGE MODELS HAVE A MORE AMPLIFIED LONGWAVE TROUGH OVER THE GREAT LAKES REGION...WIH A SUBSEQUENTLY MORE AMPLIFIED RIDGE OVER THE WEST FOR THE WEEKEND. SHORTWAVE TROUGHS EMBEDDED IN THE FLOW OVER THE WESTERN GREAT LAKES REGION MAY INTERACT WITH UNSTABLE AIRMASS SATURDAY NIGHT AND SUNDAY...SO WILL GO WITH 30 POPS FOR THIS PERIOD. UPPER FLOW BECOMES MORE ZONAL BY MIDWEEK...AND RETREATS A BIT NORTHWARD. STILL...SOUTHWEST WINDS SHOULD USHER A WARMER AIRMASS INTO THE REGION. POSSIBLE WARM FRONTAL BOUNDARY OVER THE REGION MAY BRING PRECIPITATION CHANCES...SO WILL GO WITH 30 POPS AT TIMES DURING THIS PERIOD. && .MKX WATCHES/WARNINGS/ADVISORIES... NONE. && WOOD
