SATELLITE PRECIPITATION ESTIMATES..DATE/TIME 02/12/13 0713Z SATELLITE ANALYSIS BRANCH/NESDIS---NPPU---TEL.301-683-1404 LATEST DATA USED: GOES-15: 0700Z BELGE .

EVENT...MOD TO HVY SNOWS POSSIBLE THROUGH THE OVERNIGHT PERIOD.. . SATELLITE ANALYSIS AND TRENDS...OVERALL PICTURE SHOWS UL VORT SHIFTING EASTWARD THROUGH SRN AZ AND INTO SRN NM ATTM LEADING TO HEIGHT FALLS THROUGH THE TX/OK PANHANDLES. SFC ANALYSIS SHOWING LL WINDS OUT OF THE ESE THROUGH W/CNTRL TX HELPING TO TRY AND ADVECT IN SOME HIGHER MOISTURE TOWARDS THE PANHANDLE REGION. STLT DERIVED WINDS DEPICTING A SW TO NE ORIENTED 130KT UL JET STREAK SITUATED ACROSS S/CNTRL TX. THIS IS LEADING TO INCREASED UL DIFFLUENCE ACROSS THE REGION AS PRECIP HAS STARTED TO DEVELOP THROUGH NRN TX AND INTO THE TX/OK PANHANDLES AND EXTREME ERN NM. IR IMAGERY SHOWS SOME GOOD CLOUD TOP ENHANCEMENT WITH THE BAND OF SNOW THROUGH THE NRN TX PANHANDLE AND INTO NW OK. THIS BAND SHOULD BE PRODUCING MOD TO LOCALLY HVY SNOW AS IT MOVES THROUGH WITH SNOWFALL RATES OF AROUND 1"/HR TO POSSIBLY EVEN 2"/HR. WITH TEMPS IN THE MID 30'S FOR THE MOST PART AROUND THE REGION, SNOW RATIOS SHOULD BE A BIT LOWER ATTM UNTIL THE COLDER AIR BEGINS TO FILTER IN. . SHORT TERM OUTLOOK VALID 0715-1115Z...MEDIUM CONFIDENCE FACTOR IN SHORT TERM OUTLOOK...MOST IMMEDIATE CONCERN IS FOR BAND OF MOD TO HVY SNOW MOVING NORTHEASTWARD THROUGH THE PANHANDLE REGION ATTM. OVERALL, PRECIP WILL INCREASE IN COVERAGE THROUGHOUT THIS REGION IN THE OVERNIGHT HRS OUT AHEAD OF UL SYSTEM. WITH PLENTY OF UL DYNAMICS TO WORK WITH AND WITH LL MOISTURE INCREASING A BIT THROUGH THE REGION, MOD TO HVY SNOWFALL WILL BE EXPECTED THROUGH THE PRE-DAWN HRS. CURRENT THINKING IS THAT HEAVIEST SNOW SHOULD BE THROUGH THE CNTRL PANHANDLES AND INTO WRN OK AS DEFORMATION ZONE BEGINS TO SET UP. IN GENERAL SNOWFALL RATES SHOULD BE AROUND 1"/HR WITH SLIGHTLY HIGHER RATES IN THE HEAVIEST SNOW BANDS. . ....NESDIS IS A MEMBER OF 12 PLANET.... .
