AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PUEBLO CO 309 PM MDT FRI SEP 28 2007 .SHORT TERM... (TONIGHT AND SATURDAY) CURRENTLY...ISOLATED STRONG CONVECTION DEVELOPING OVER KIOWA COUNTY ALONG EAST-WEST ORIENTED AXIS OF ENHANCED INSTABILITY NORTH OF THE ARKANSAS RIVER. OTHER WEAKER CONVECTION MOVING FROM THE SANGRES ONTO THE PLAINS...THOUGH INSTABILITY IS MUCH LESS SOUTH OF THE ARKANSAS RIVER AND WEST OF KLHX. OTHER AREA OF CONVECTION MOVING ACROSS THE NM BORDER FROM SOUTH OF KDRO TO SOUTH OF KALS IN RESPONSE TO INCREASING UPWARD MOTION FROM THE UPPER TROUGH DIGGING INTO THE GREAT BASIN. MAIN SEVERE THREAT THROUGH EARLY EVENING LOOKS TO BE LIMITED TO POCKET OF DEEPER INSTABILITY OVER PROWERS/KIOWA COUNTIES...WITH PERHAPS A SLIGHT RISK OVER BACA/BENT/LAS ANIMAS IF DEEPER INSTABILITY OVER NORTHERN NM CAN ADVECT NORTHWARD. TONIGHT...ISOLATED TO SCATTERED -TSRA THIS EVENING AREAWIDE...WITH LINGERING -SHRA PAST 06Z AS WEAK UPWARD MOTION CONTINUES. HIGHEST POPS OVER THE SAN JUANS AND SAWATCH RANGE...WITH FAVORABLE OROGRAPHICS AND CLOSER PROXIMITY TO THE UPPER TROUGH. FAIRLY MILD TEMPS OVERNIGHT AS AIR MASS NEVER COMPLETELY DECOUPLES...PLUS RATHER WIDESPREAD CLOUD COVER. .SATURDAY...UPPER TROUGH LIFTS OUT OF THE GREAT BASIN DURING THE DAY...MOVING INTO EXTREME NORTHWEST COLORADO BY LATE AFTERNOON. MAIN UPPER JET WILL MOVE ACROSS THE AREA DURING THE DAY...WITH DEEP SOUTHWEST FLOW FROM THE SURFACE THROUGH 300 MB DEVELOPING. EXPECT WINDS TO REALLY CRANK UP BY MID-MORNING...WITH DEEP MIXING PROMOTING VERY GUSTY CONDITIONS THROUGH THE DAY. GUSTS OF 40 TO 50 MPH OVER THE EASTERN MOUNTAINS AND ACROSS THE PLAINS ARE LIKELY...A FEW 60 MPH GUSTS NOT OUT OF THE QUESTION OVER THE HIGHER PEAKS. BOTH NAM AND GFS KEEP THE BOUNDARY LAYER FAIRLY MOIST THROUGH THE DAY OVER THE PLAINS...WHICH MAY BE OVERDONE GIVEN THE USUALLY DRY DOWNSLOPE SOUTHWESTERLY FLOW. WILL KEEP THE LOW POPS IN PLACE FOR NOW...BUT WONT GO ANY HIGHER THAN ISOLATED AT THIS POINT. STRONG SHEAR/WINDS ALOFT COULD CERTAINLY ENHANCE THE SEVERE WIND THREAT OVER THE FAR EAST NR THE KS BORDER IN THE AFTERNOON...THOUGH INSTABILITY LOOKS VERY MARGINAL. BETTER PRECIP CHANCES OVER THE CENTRAL AND SOUTHWEST MOUNTAINS...WITH SOUTHWEST FLOW A MORE FAVORABLE DIRECTION FOR OROGRAPHIC PRECIP...AT LEAST ALONG THE CONTINENTAL DIVIDE. SNOW LEVEL WILL START OUT VERY HIGH (12K FEET)...LIMITING ANY ACCUMULATIONS TO THE HIGHEST PEAKS DURING THE DAYTIME HOURS. -EP- .LONG TERM... (SATURDAY NIGHT THROUGH FRIDAY) TROUGH AXIS OVER WESTERN COLORADO BY 00Z SUNDAY WITH MAIN FOCUS OF PRECIPITATION IN NORTHERN COLORADO INTO OUR CENTRAL MOUNTAINS. HAVE MAINTAINED SCATTERED TO ISOLATED POPS OVER CWFA THROUGH THE FIRST HALF OF THE NIGHT...THEN TRAILING OFF INTO ISOLATEDS...WHICH MAY BE OVERDONE THROUGH 12Z SUNDAY. COULD SEE AN INCH OR SO OF SNOW IN THE HIGHER ELEVATIONS OF THE CENTRAL MOUNTAINS. MAIN INFLUENCE FROM THE COMPACT...BUT VIGOROUS SYSTEM...WILL BE STRONG WINDS. WINDS WILL LIKELY BE GUSTING OVER 40 MPH OVER PARTS OF THE PLAINS...AND 50 TO 60 MPH OVER THE HIGHER TERRAIN DURING THE EARLY EVENING. RELATIVE HUMIDITIES WILL BE FAIRLY LOW IN THE EARLY EVENING...BUT ABOVE 25 PERCENT. AS WE HAVE SEEN FROM THIS PAST WEEK...FIRES CAN STILL START WITH THESE CONDITIONS...SO THIS PART OF THE FORECAST WILL NEED TO BE WATCHED CLOSELY. CRITICAL FIRE WEATHER POTENTIAL WILL BE POSSIBLE. WIND SPEEDS AND GUSTS OVERNIGHT WILL DEPEND ON IF/WHEN THERE IS SOME DECOUPLING. MODEL SOUNDINGS SHOW THAT SOME DECOUPLING WILL OCCUR...SO WIND GUST FORECAST IN LINE WITH SURROUNDING OFFICES WITH GUSTS TAILING OFF BELOW 25 MPH. WINDS WILL ALSO SWING AROUND NORTH OF WEST...AS TROUGH AXIS MOVES PAST EASTERN COLORADO AND DRIER AIR POURS IN. SUNDAY LOOKS TO BE A FAIRLY NICE DAY AFTER THE SWIFT MOVING DISTURBANCE. VERY DRY AIR FORECAST BY MODELS TO BE OVER CWFA...WITH MID LEVEL TEMPERATURES EXPECTED IN THE 8 TO 10 DEGREE CELSIUS RANGE...AND FAIRLY LIGHT WINDS. CHANGE FROM PREVIOUS OUTPUT IS A LITTLE SLUG OF MOISTURE MOVING IN FROM THE SOUTH OVERNIGHT. THE NAM12 MORE AGGRESSIVE...PRINTING OUT MEASURABLE RAIN OR SNOW IN THE WESTERN PART OF THE AREA TOWARD DAWN...WHILE GFS HOLDS OFF A BIT LONGER. CHOSE TO HOLD OFF ON INTRODUCING POPS ATTM. ON MONDAY...MOISTURE IS OVER THE AREA...BEING PULLED NORTHWARD IN ADVANCE OF ANOTHER VIGOROUS NORTHERN SHORT WAVE. PUT IN ISOLATED POPS OVER THE ENTIRE AREA BY MIDDAY...BUT IT COULD HAPPEN SOONER. TEMPERATURES WILL BE QUITE WARM AHEAD OF THE SHORT WAVE. MONDAY NIGHT INTO TUESDAY MORNING...THE SHORT WAVE MOVES OVER THE AREA...AND HAVE ISOLATED TO NEAR LOW CHANCE POPS. ITS POSSIBLE THAT A FAIRLY SOLID BAND OF RAIN/SNOW SHOWERS...WITH A LITTLE THUNDER...WOULD OCCUR AS THE SYSTEM MOVES THROUGH...BUT AS THE EVENT NEARS...THAT SCENARIO COULD BE MORE EVIDENT. AFTER THAT SHORT WAVE...MODELS FORECASTING MODERATE WEST TO WEST- SOUTHWEST FLOW ALOFT...ALONG WITH MILD TEMPERATURES FOR EARLY OCTOBER. HIGH TEMPERATURES WILL RANGE FROM THE 50S IN THE HIGHEST ELEVATIONS TO THE LOWER 80S ACROSS THE SOUTHEAST PLAINS. -TLM- && .AVIATION...EXPECT ISOLATED -TSRA/-SHRA OVER THE AREA THIS EVENING WITH SOME LINGERING -SHRA OVERNIGHT...THOUGH MORE WIDESPREAD ACTIVITY WILL REMAIN SOUTH AND EAST OF BOTH KPUB AND KCOS TERMINALS. LOW LEVELS OF THE ATMOSPHERE ARE FAIRLY DRY...SO MAINLY BRIEF MVFR CONDITIONS AT WORST WITH ANY STORMS. BREEZY TO WINDY CONDITIONS WILL DEVELOP BY MIDDAY SATURDAY AS LOW PRESSURE DEEPENS OVER THE PLAINS. && .PUB WATCHES/WARNINGS/ADVISORIES... NONE. && 10/13
