&&
.PREV DISCUSSION... /ISSUED 353 AM CST FRI MAR 2 2007/
DISCUSSION...
DEEP SURFACE LOW MOVING THROUGH SOUTHWEST WI AT THIS TIME AND JUST
A TOUCH DEEPER THAN MODELS EARLY IN PERIOD. BROAD ISENTROPIC LIFT
ON 285 SURFACE FORECAST INTO CWA INTO TONIGHT BUT WITH A GRADUAL
DECREASE. AROUND 2 G/KG INDICATED BY RUC INTO EASTERN HALF OF MN
THROUGH THE MORNING SUGGESTS BETTER ACCUMULATION POSSIBILITY IN
EASTERN CWA. A NEW AREA OF HIGHER REFLECTIVITY SPINNING WEST AT
THIS TIME. WINDS HAVE BEEN INCREASING OVER WESTERN MN WITH WDL
PROFILER SHOWING AN INCREASE TO 30 KNOTS IN THE LOWEST GATE IN THE
LAST 2 HOURS. WINDS A BIT MARGINAL FOR BLIZZARD CRITERIA BUT
STEEPER LOW LEVEL LAPSE RATES INDICATED FROM NW IA INTO SW MN.
WITH THE AREA OF FRONTOGENESIS AND CONTINUING SNOW...SEEMS
APPROPRIATE TO KEEP GOING..ESPECIALLY IN A FAVORED AREA FOR WIND.
IT IS POSSIBLE THAT SOME HIGHLIGHTS COULD BE TRIMMED ELSEWHERE
THIS AFTERNOON IF SNOW DECREASES ENOUGH.
SNOW CHANCES DECREASE FAIRLY RAPIDLY LATER TONIGHT AS ISENTROPIC
LIFT REGION ROTATES SOUTHEAST OF AREA. GOOD LOW LEVEL DRYING
MOVING IN FOR LATER SATURDAY. GENERALLY QUIET
WEATHER...COMPARITIVLEY...SHAPING UP FOR NEXT FEW DAYS. PLENTY OF
ARCTIC AIR SITTING IN NW CANADA THOUGH...COULD CAUSE SOME
PROBLEMS IN FORECAST IF COLD AIRS OOZES FARTHER SOUTH THAN MODELS
INDICATE. THIS FRONT MAKES IT INTO AREA ON MONDAY...AND HINT OF
SOME WARM ADVECTION FOR MONDAY NIGHT AND TUESDAY. EXPANDED SMALL
CHANCE OF LIGHT SNOW FOR NORTHEAST CWA ON TUESDAY. SOME MILDER
PACIFIC AIR PUSHING INTO THE AREA WEDNESDAY AND PART OF
THURSDAY...BUT ARCTIC BOUNDARY STILL NOT TOO FAR AWAY.
&&
.AVIATION...
CONCERNS FOR TAFS ARE REDUCTION TO VISIBILITIES DUE TO SNOW AND
BLOWING SNOW. SHOULD BE PREDOMINANT MVFR VISBYS DUE TO PRIMARILY
BLOWING SNOW THROUGHOUT THE DAY...HOWEVER THE OCCASIONAL SNOW BAND
WILL BRING IFR VISBYS TO THE TERMINALS THAT THEY PASS. IT IS A
CHALLENGE PINNING DOWN WHEN EXACTLY THESE WILL OCCUR GIVEN THEY
ARE FORMING AROUND TWIRLING LOW CENTER OVER SOUTH CENTRAL
WISCONSIN. HAVE FOLLOWED CURRENT SATELLITE AND RADAR TRENDS FOR
THE FIRST FEW HOURS OF THE TAFS. BEYOND THAT HAVE GUIDED ON SHORT
TERM MODEL PLACEMENT OF BANDS OF FORCING THROUGH THE AFTERNOON.
CIGS SHOULD STAY GENERALLY MVFR OR EVEN VFR AT TIMES...ONLY
FLIRTING WITH IFR UNDER THE MODERATE SNOW BANDS. NORTH TO
NORTHWEST WINDS SHOULD INCREASE EVEN MORESO BY 15Z WITH GUSTS
EXPECTED THROUGH THIS EVE. RWF IN THE FAVORED MINNESOTA RIVER
VALLEY HAS THE CHANCE TO SEE EVEN HIGHER GUSTS THAN
FORECASTED...BUT THE MOST FAVORABLE PROFILE STILL REMAINS ON TOP
OF AND ON THE OTHER SIDE OF BUFFALO RIDGE SO CONTINUE TO KEEP
GUSTS AROUND 30KT ONLY. BLOWING SNOW AGAIN WILL CONTINUE INTO
EARLY THIS EVE. BEYOND TAF CYCLE LIFTING AND SCOURING OF CLOUDS IS
EXPECTED DURING SAT MORNING.
