What 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 Green Bay, WI wrote its last area forecast discussion before this severe thunderstorm warning went out at May 28, 12:51 PM CDT, 2 hours 19 minutes earlier.

Area forecast discussion, May 28, 12:51 PM CDT, 2 hours 19 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
1251 PM CDT MON MAY 28 2012

UPDATED AVIATION PORTION FOR 18Z TAF ISSUANCE

.SHORT TERM...
TODAY THROUGH TUESDAY. A COLD FRONT OVER MINNESOTA WILL BRING THE
THREAT OF SHOWERS AND THUNDERSTORMS TODAY AS IT MOVES SLOWLY EAST.
LOW LEVEL CONVERGENCE ALONG THE FRONT WEAKENS WITH TIME AND THERE
IS ACTUALLY WEAK COLD ADVECTION BY THE END OF THE DAY. THESE
FACTORS ARGUE AGAINST SIGNIFICANT PRECIPITATION BUT THE SYSTEM
DOES HAVE SOMETHING GOING FOR IT...THE RIGHT ENTRANCE REGION OF A
VIGOROUS UPPER JET IS FORECAST TO MOVE ACROSS THE AREA THIS
AFTERNOON. ALL IN ALL THE BEST DYNAMICS LOOK TO BE IN THE EASTERN
HALF OF THE FORECAST AREA THIS AFTERNOON. THE SEVERE THREAT WILL
DEPEND ON HOW MUCH SURFACE HEATING WE GET AND HOW MUCH LOW LEVEL
MOISTURE THERE IS. THE MAIN SEVERE WEATHER THREAT WOULD BE WINDS
AND HAIL. HIGHS TODAY SHOULD BE WARMER THAN YESTERDAY OVER ALL
BUT THE SOUTHERNMOST COUNTIES.

THE FRONT MOVES THROUGH TONIGHT BUT MAIN PUSH OF COLD AIR LAGS
BEHIND QUITE A BIT. SOME LEFTOVER SHOWERS POSSIBLE IN THE EAST
DURING THE EVENING. LOWS SHOULD BE A FEW DEGREES ABOVE NORMAL FOR
THIS TIME OF THE YEAR.

BLUSTERY AND COOLER TUESDAY AS 850MB TEMPERATURES FALL THROUGH THE
SINGLE NUMBERS DURING THE DAY. THE LEFT EXIT REGION OF AN UPPER
JET IS FORECAST TO MOVE ACROSS NORTHERN WISCONSIN AND MIGHT BE
SUFFICIENT TO PRODUCE SOME SCATTERED SHOWERS.

.LONG TERM...TUESDAY NIGHT THROUGH SUNDAY.

COLD AIR MOVING OVER LAKE SUPERIOR IN CYCLONIC FLOW BEHIND A
DEPARTING SURFACE COLD FRONT AND LOW WILL KEEP A CHANCE OF SOME
SHOWERS ACROSS NORTH CENTRAL WISCONSIN ON TUESDAY NIGHT. EVEN
WITHOUT PRECIPITATION...THERE SHOULD BE ENOUGH CLOUDS AND WIND TO
HOLD TEMPERATURES UP AND KEEP FROST FROM DEVELOPING. SKIES SHOULD
BEGIN TO CLEAR ON WEDNESDAY WITH SURFACE HIGH PRESSURE AND A WEAK
UPPER RIDGE OVER WISCONSIN. A SYSTEM APPROACHING FROM THE PLAINS
WILL BRING AN INCREASE IN CLOUDS TO THE SOUTHERN PART OF THE
AREA ON WEDNESDAY NIGHT. A COLD AIRMASS...LIGHT WINDS AND PARTLY
CLOUDY SKIES SHOULD ALLOW AT LEAST PATCHY FROST TO DEVELOP ACROSS
MUCH OF NORTHERN WISCONSIN.

THE MAIN ISSUE FROM THURSDAY THROUGH SUNDAY IS RUN-TO-RUN MODEL
CONSISTENCY. THE LATEST MODEL RUNS LOOK WETTER THAN THEY DID 24
HOURS AGO...SO HAVE OPTED TO LEAVE THE BLENDED MODEL SOLUTION
ALONE DURING THIS PART OF THE FORECAST. THIS APPROACH YIELDS AREAS
OF AT LEAST SLIGHT CHANCE POPS IN THE GRIDS FOR MOST PERIODS.
CLOUDS SHOULD GENERALLY HELP TO KEEP LOW TEMPERATURES FROM
FALLING BELOW NORMAL. HIGHS WILL BE ON THE COOL SIDE FOR THE END
OF THE WORK WEEK...BEFORE WARMING UP OVER THE WEEKEND.
&&

.AVIATION...SCATTERED THUNDERSTORMS WILL MOVE ACROSS NORTH CENTRAL
AND NORTHEAST WISCONSIN DURING THE REMAINDER OF THE AFTERNOON INTO
EARLY THIS EVENING. SOME OF THESE STORMS COULD PRODUCE LARGE HAIL
AND DAMAGING WINDS IN EXCESS OF 50 KNOTS. VFR CONDITIONS SHOULD
PREVAIL AFTER THE STORMS EXIT THE REGION. BETWEEN 04Z AND 07Z...
SOME MODEL GUIDANCE SUGGEST THAT THERE IS SOME POTENTIAL FOR A
PERIOD OF GUSTY WINDS OF 15 TO 25 KNOTS. THESE WINDS WILL CONTINUE
FOR MOST THE REMAINDER OF THE NIGHT...ALTHOUGH COULD BE A PERIOD
JUST BEFORE OR AROUND SUNRISE THAT THE WINDS DECOUPLE FOR A BRIEF
PERIOD. WINDY CONDITIONS EXPECTED ON TUESDAY WITH GUSTS TO AROUND
30 KNOTS POSSIBLE. MVFR CIGS EXPECTED TO MOVE INTO NORTH CENTRAL
WISCONSIN TUESDAY. SCATTERED TO ISOLATED SHOWERS EXPECTED NORTH
OF A MERRILL TO MARINETTE LINE ON TUESDAY...ESPECIALLY DURING THE
AFTERNOON HOURS.

ECKBERG
&&

.MARINE...SMALL CRAFT WILL BE ISSUED FOR MEMORIAL DAY...FROM
10 AM TO 6 PM. GUSTY SOUTH/SOUTHWEST WINDS CAN BE EXPECTED WITH
SOME GUSTS TO AROUND 25 KNOTS BY LATE MORNING THROUGH MUCH OF THE
AFTERNOON. &&

.GRB WATCHES/WARNINGS/ADVISORIES...
NONE.
