NATIONAL WEATHER SERVICE GREEN BAY WI
1210 PM CST WED FEB 8 2012

UPDATED 

MORNING SOUNDING FAIRLY DRY SURFACE TO 975MB. MIXING HAS TAPPED
INTO THIS AIR WITH DEW DROPPING THROUGH MORNING ESPECIALLY OVER
NORTH CENTRAL WI. THIS SIMILAR TO WHAT OCCURRED YESTERDAY OVER
ARROWHEAD. HAVE UPDATED GRIDS THROUGH AFTERNOON TO REFLECT LOWER
DEWS AND SLIGHTLY WARMER TEMPS.

AVIATION PORTION UPDATED FOR 18Z TAF ISSUANCE

.SHORT TERM...TODAY THROUGH THURSDAY. HIGH PRESSURE MOVING SOUTH
ACROSS THE PLAINS WILL KEEP DRY SEASONABLE WEATHER IN CENTRAL AND
NORTHERN WISCONSIN TODAY AND TONIGHT. THURSDAY SHOULD BE MILDER AS
SOUTHERLY FLOW INCREASES AHEAD OF AN APPROACHING COLD FRONT.

.LONG TERM...THURSDAY NIGHT THROUGH NEXT TUESDAY. THE SPLIT FLOW
WINTER LOOKS TO CONTINUE WELL INTO NEXT WEEK IF YOU BELIEVE THE
MEDIUM RANGE MODELS. THIS MEANS ONLY BRIEF PUSHES OF ARCTIC AIR
AND NO SIGNIFICANT STORMS FOR OUR AREA. 

AN UPPER TROUGH WILL DROP SOUTH ACROSS THE REGION FRIDAY AND
BRING IN A COUPLE DAYS OF COLDER THAN NORMAL AIR AND SOMEWHAT
COLD WIND CHILLS. TEMPERATURES WILL CLIMB SUNDAY AND MONDAY AS
UPPER RIDGE EDGES IN FROM THE WEST. THE MODELS LIFT AN UPPER
SYSTEM FROM THE SOUTHERN PLAINS TUESDAY AND WEDNESDAY WHILE AN
UPPER TROUGH DROPS SOUTHEAST IN THE NORTHERN STREAM. THE TWO
SYSTEMS LOOK TOO FAR APART FOR SIGNIFICANT PHASING TO OCCUR...BUT
WE SHOULD SEE AN INVERTED TROUGH MOVE ACROSS THE MIDWEST AND GREAT
LAKES AND POSSIBLY BRING US A COUPLE INCHES OF WET SNOW.
&&

.AVIATION...CLEAR SKIES THROUGH THURSDAY. THERE WILL BE SOME LOW
LEVEL WIND SHEAR AFTER DARK TONIGHT WITH SURFACE WINDS FROM THE
WEST AT 5 TO 10 KNOTS AND WEST WINDS OF 25 TO 30 KNOTS AT 800 TO
1200 FT AGL.
