What forecasters said that day

NWS North Platte, NE wrote its last area forecast discussion before this ice storm warning went out at Feb 19, 3:44 AM CST, 11 hours 54 minutes earlier.
Area forecast discussion, Feb 19, 3:44 AM CST, 11 hours 54 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORTH PLATTE NE 344 AM CST SAT FEB 19 2011 .SYNOPSIS...WATER VAPOR IMAGERY AT 07Z SHOWING VIGOROUS UPPER LEVEL TROUGH OFF THE SOUTHWEST PACIFIC COAST WITH 100KT+ JET COMING ONSHORE. AT THE SURFACE...A FRONTAL BOUNDARY WAS ANALYZED FROM CENTRAL WYOMING AND ROUGHLY EAST ALONG THE SOUTH DAKOTA/NEBRASKA BORDER. TEMPERATURES AND DEWPOINTS SOUTH OF THE FRONT WERE GENERALLY IN THE UPPER 20S AND LOW 30S...WHILE LOCATIONS TO THE NORTH WERE IN THE TEENS. && .DISCUSSION...FORECAST FOCUSED ON IMPENDING STORM SYSTEM TO AFFECT THE AREA BEGINNING THIS EVENING. ENERGY WILL EJECT OUT OF THE WESTERN CONUS TROUGH TODAY WHICH WILL CAUSE LEE-SIDE CYCLOGENESIS OVER EASTERN COLORADO TONIGHT. THE EXACT TRACK OF THE SYSTEM CONTINUES TO BE IN QUESTION THUS DECIDED TO HOLD ON TO THE WINTER STORM WATCH UNTIL A BIT MORE CONSENSUS IS SEEN WITH THE MODELS. THE FAVORED TRACK WOULD TAKE THE SURFACE LOW ACROSS SOUTHERN NEBRASKA TONIGHT AND INTO IOWA ON SUNDAY. THIS EVENING A 40 TO 50KT LOW LEVEL JET WILL SET UP WITH ITS FOCUS INTO SOUTHERN NEBRASKA. THIS WILL PUMP MOISTURE INTO THE AREA...CAUSING DEWPOINTS TO RISE INTO THE MID 30S AND LOW 40S ACROSS SOUTHERN NEBRASKA. MODELS ARE INDICATING UP TO 800 G/KG OF MOST UNSTABLE CAPE...MAINLY ACROSS THE SOUTHEAST HALF OF THE FORECAST AREA SO THINKING THUNDERSTORMS WILL OCCUR IN THESE AREAS THIS EVENING. SHEAR WILL BE PLENTIFUL WITH 100KT+ JET ALOFT SO MAY BE A BIT STRONG FOR THE CAPE AVAILABLE. CAN/T DISCOUNT THE POSSIBILITY OF SOME STRONGER STORMS WITH PERHAPS SOME HAIL...BUT DON/T THINK THERE IS A SUBSTANTIAL SEVERE THREAT. AS THE SYSTEM PROGRESSES EAST TONIGHT THE COLDER AIR UP TO THE NORTH WILL COME SOUTHWARD INTO THE AREA WHICH WILL BRING A VARIETY OF WINTER WEATHER TYPES TO THE FORECAST AREA. WITH THE FAVORED TRACK...ONCE THE COLDER AIR INTRUDES...TEMPERATURE PROFILES INDICATE THAT THERE WILL BE A PERIOD OF SLEET AND/OR FREEZING RAIN BEFORE THE ENTIRE COLUMN SATURATES CHANGING THE PRECIPITATION TO SNOW. CURRENT INDICATIONS ARE THAT THE WORST OF THE ICING WOULD BE REALIZED ACROSS THE NORTHERN TIER OF COUNTIES. ALTHOUGH PRECIPITATION AMOUNTS LOOK TO BE LIGHTER GOING SOUTH...SOUNDINGS WERE SHOWING THE POSSIBILITY FOR FREEZING RAIN OR FREEZING DRIZZLE ACROSS THE ENTIRE FORECAST AREA FOR A PORTION OF THE TIME. STRONG COLD AIR ADVECTION BEHIND THE SYSTEM WILL CAUSE THE COLUMN TO COOL PRETTY QUICKLY ON SUNDAY...SO EXPECTING ALL PRECIPITATION TO SWITCH TO SNOW BY SUNDAY AFTERNOON. IN ADDITION...A STRONG PRESSURE GRADIENT WILL SET UP AS THE LOW MOVES EAST AND THEREFORE EXPECTING PRETTY WINDY CONDITIONS BEGINNING SUNDAY MORNING AND CONTINUING THROUGH A PORTION OF SUNDAY NIGHT. DID ADD BLOWING SNOW INTO THE FORECAST FOR LOCATIONS WHERE SNOWFALL ACCUMULATIONS ARE EXPECTED AS VISIBILITIES WILL LIKELY BE HAMPERED BY THESE CONDITIONS. LOOKING FOR LIGHT SNOW TO LINGER INTO THE MORNING HOURS ON MONDAY ACROSS NORTHERN NEBRASKA...THEN COLDER /AND CLOSER TO NORMAL/ TEMPERATURES WILL STICK AROUND FOR THE WEEK. WITH THE LARGE TROUGH REMAINING ACROSS THE WESTERN CONUS...ANOTHER STORM SYSTEM LOOMS ON THE HORIZON WITH CURRENT MODELS BRINGING IT ACROSS THE CENTRAL PART OF THE COUNTRY AT THE MIDDLE OF NEXT WEEK. && .AVIATION... ARCTIC FRONT DRAPED JUST NW OF KVTN WITH LEADING EDGE OF STRATUS OVC015 LOCATED NEAR 65SM NW OF KVTN. LOOKS LIKE 15Z IS WHEN MVFR STRATUS WILL WORK INTO KVTN...WHICH SHOULD PERSIST THROUGH REMAINDER OF TAF CYCLE. AS STORM SYSTEM APPROACHES...SOUNDINGS INDICATE COLD ENOUGH FOR -FZRA OR -IP AFT 03Z WITH CIGS INTO IFR CATEGORY. KLBF TO SEE INCREASE IN MID/HIGH CLOUDS THROUGH 0Z/20TH. STRONG ISENTROPIC LIFT SHOULD BRING MVFR CIGS NEAR OVC020 AFT 00Z/20TH. THEN AFT 03Z...TSRA PLANNED AS PREVAILING PER LIKELY POPS IN GRIDDED FCST. && .LBF WATCHES/WARNINGS/ADVISORIES...WINTER STORM WATCH FROM THIS EVENING THROUGH SUNDAY EVENING FOR NEZ004>010-094. && SHORT TERM/EXTENDED...BROOKS AVIATION...ROBERG
