Area forecast discussion, Apr 15, 9:53 AM CDT, 5 hours 13 minutes before
AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE HASTINGS NE
953 AM CDT SAT APR 15 2006
.DISCUSSION...QUICK UPDATE TO INCREASE WIND SPEEDS AND ISSUE A
WIND ADVISORY FOR AREAS WEST AND SOUTHWEST. WIND WITH HIGH
MOMENTUM WILL BE MIXED DOWN BY AFTERNOON.
&&
.PREV DISCUSSION... (ISSUED 358 AM CDT SAT APR 15 2006)
DISCUSSION...THIS FORECAST DEALS PRIMARILY WITH THE RISK OF
SEVERE TODAY...WITH THE OUTLIER OF WIND PROBLEMS AS WELL.
A LOT GOING ON. NAM STILL THE SLOWEST AND BELIEVE IT TO BE TOO SLOW
GIVEN LIGHTNING STRIKES JUST WEST OF I-25 NEAR PUEBLO AT 08Z.
CENTER OF UPPER LEVEL LOW PRESSURE APPROACHING SOUTHEAST UTAH.
NAM ALSO WAY TOO HIGH ON LOW LEVEL MOISTURE. IT FORECASTS SURFACE
DEW POINTS WELL INTO THE 60S WITH H85 DEW POINTS NEAR 15C. THERE
IS NOTHING IN THE LOW LEVEL MOISTURE ANALYSIS TO SUGGEST THIS WILL
HAPPEN...AND WE MAY WELL MIX THE LOWER ATMOSPHERE FURTHER AND THUS
WATER DOWN WHAT LOW LEVEL MOISTURE WE WILL HAVE. GFS HAS MUCH
BETTER HANDLE ON MOISTURE...AS DOES THE 06Z RUC.
WHILE A VAST MAJORITY OF THE CWFA IS CONSIDERED A MODERATE RISK FOR
SEVERE WEATHER...THIS FORECAST KEEPS SEVERE POTENTIAL CONFINED TO THE
NORTHERN/EASTERN 1/2 OF THE CWFA...AND THAT MAY TOO GENEROUS.
PRIMARY REASONS ARE SPEED OF THE SYSTEM...WEAK MOISTURE PARAMETERS
AND INITIAL CAPPING. AM TRENDING TOWARD THE QUICKER GFS/RUC IDEAS
AT THIS TIME.
SCENARIO SHOULD UNFOLD WITH DRY LINE SURGE AROUND 18Z REALLY PUSHING
THROUGH THE SOUTHWEST 1/4 TO 1/3 OF THE CWFA. THIS RAPID PUSH MAY
WARRANT WIND ADVISORY IN THE SOUTHWEST ZONES. RUC/ETA BOTH SUGGEST
STRONG H85 WINDS WELL ALIGNED IN THE LATE MORNING AND EARLY
AFTERNOON...BUT 06Z ETA DOES NOT KEEP THINGS GOING IN THE LATE
AFTERNOON (AT LEAST NOT NECESSARILY ADVISORY LEVEL WINDS). DAY SHIFT
WILL HAVE TO MONITOR WIND SITUATION...AS CONFIDENCE IS JUST A BIT
LOW ON THIS SHIFT REGARDING THE TIMING AND LOCATION OF STRONGEST
WINDS LATER TODAY.
AS THE DRY LINE RIFLES EAST...STRONG UPPER SUPPORTED ASCENT WILL
OVERCOME THE AREA. THIS SHOULD BE ENOUGH FOR SCATTERED
THUNDERSTORM DEVELOPMENT...ESPECIALLY ACROSS THE EASTERN/NORTHERN
CWFA. AS MENTIONED YESTERDAY...THIS LOOKS A LOT LIKE THE MARCH
30TH EVENT WITH TURNED OUT TO BE MARGINALLY SEVERE HAIL AND SOME
WIND EVENTS. BEST SHEAR IS EAST OF THE CWFA BY 00Z...AND ONLY
FAVORS THE CWFA IN THE AFTERNOON HOURS. TORNADO RISK APPEARS SMALL
WITH LIMITED DISCRETE SUPERCELLS AND ONLY A SMALL WINDOW OF
OPPORTUNITY. MAIN RISK MAY BE JUST TO THE NORTH DEPENDING ON HOW THIS
STORM WRAPS UP...AND TO THE EAST IN DEEP LAYER SHEAR AND BETTER
MOISTURE DURING EVENING. MODERATE RISK FROM SPC PRECLUDES ANY
LARGE DEVIATION AND WILL KEEP SEVERE MENTION...BUT BELIEVE THERE
IS CAUSE FOR SOME DOUBTS REGARDING WIDESPREAD EVENT OVER THE
HASTINGS CWFA. WE WILL KNOW MORE IN ABOUT 15 HOURS.
RISK FOR SEVERE WEATHER SHOULD PASS/END BY MID EVENING LEAVING
THE CWFA IN FOR A BREEZY/WINDY NIGHT WITH SOME LINGERING SHOWERS.
NAM STILL THE SLOWEST AND LINGERS SHOWERS IN THE EASTERN CWFA
EARLY SUNDAY MORNING. WILL LEAVE DRY FOR NOW...CLOUDS WILL
ENCOMPASS MUCH OF THE CWFA AT SUNRISE ON EASTER SUNDAY WITH
BRISK WINDS ACROSS THE BOARD. WINDS WILL SLOWLY LESSEN FROM
WEST TO EAST THROUGHOUT THE DAY...WITH CLOUDS DOING JUST THE
SAME.
MONDAY LOOKS LIKE A NICE ONE AGAIN. MODELS CONTINUE TO DEPICT
SYSTEM ALONG ABOUT TUESDAY/WEDNESDAY WILL CONTAIN A LARGE
PART OF ITS ENERGY WITH THE UPPER LOW ACROSS THE NORTHERN
PLAINS. THOUGH COOLER...THIS GENERALLY IS NOT A FAVORED
TRACK FOR MUCH IN THE WAY OF PRECIPITATION.
