Area forecast discussion, Jun 19, 2:52 AM CST, 8 hours 48 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GOODLAND KS
252 AM MDT TUE JUN 19 2007

.DISCUSSION...A RIDGE TO THE WEST WILL KEEP NORTHWEST FLOW OVER THE
CENTRAL PLAINS THROUGH THIS FORECAST. A SURFACE TROUGH WILL BE IN
COLORADO AND HIGH PRESSURE TO THE EAST. HIGH PRESSURE WILL SHIFT
FURTHER EAST ON WEDNESDAY WHILE LOW PRESSURE REMAINS OVER
COLORADO/WYOMING.

POPS ARE THE MAIN QUESTION FOR THIS FORECAST.

SHORTWAVE ENERGY FOR TODAY IS DIFFICULT TO PINPOINT...ALTHOUGH THERE
IS SOME INDICATION OF AN APPARENT SHORTWAVE ENTERING WESTERN WYOMING
AT THIS TIME AND SHOULD BE AVAILABLE FOR MAX HEATING THIS AFTERNOON.
THERE IS ENOUGH MOISTURE/CAPE AND INSTABILITY. JET DYNAMICS ARE
WEAK. A SURFACE FRONT LIES SOUTHEAST OF THE FORECAST AREA AND THIS
COULD MOVE BACK NORTHWEST WITH SOUTHEAST WIND TODAY. ANOTHER
POSSIBLE BOUNDARY WOULD BE THE DRYLINE WHICH IS NEAR THE HIGHER
TERRAIN JUST EAST OF THE FRONT RANGE. STEERING WIND IS ONLY ABOUT
10KTS FROM THE WEST SOUTHWEST. THINK BEST POPS SHOULD BE IN THE
DEEPER MOISTURE NEAR THE SURFACE FRONT OR IN THE EASTERNMOST ZONES.
THIS GOES ALONG WITH GUIDANCE POPS ALSO. CHANCE POPS LOOK GOOD IN
THE EAST WITH SLIGHT CHANCE POPS ELSEWHERE. BETTER DEFINED SHORTWAVE
ENERGY COMES THROUGH THE FLOW WEDNESDAY AFTERNOON/NIGHT AND AGAIN
THURSDAY NIGHT. SINCE TIMING THESE WAVES ARE DIFFICULT IN NORTHWEST
FLOW WILL GO WITH SLIGHT CHANCE POPS FOR NOW. MOISTURE IS LACKING
DURING THE DAY ON THURSDAY SO WILL KEEP THAT PERIOD DRY.

THERE IS ALSO A QUESTION CONCERNING LOW CLOUDS/FOG DEVELOPING OVER
THE FORECAST AREA THIS MORNING. DEWPOINT DEPRESSIONS ARE AT LEAST 4
DEGREES. THE NAM BOUNDARY LAYER RH FIELD INDICATES GREATER THAN 90
PERCENT RH MOVING NORTHWEST ACROSS A LARGE PART OF THE FORECAST AREA
FROM 12Z-15Z. CURRENTLY THE FOG SATELLITE PRODUCT DOES NOT SHOW ANY
DEVELOPMENT TRENDS YET. PLAN TO MONITOR AND MAKE LAST MINUTE
DECISION.

850 TEMPERATURES INDICATE THE POTENTIAL FOR READINGS IN THE 90S.
FORECAST MAX TEMPERATURES WILL WARM FROM THE MID/UPPER 80S TO THE
LOWER 90S WED/THU. MIN TEMPERATURES SHOULD BE IN THE LOWER 60S WEST
TO THE MID 60S EAST.

&&

.AVIATION...VFR CONDITIONS ARE EXPECTED TO DETERIORATE TO MVFR
CONDITIONS BY 09Z AND LAST THROUGH 16Z DUE TO AREAS OF FOG. THIS
WILL OCCUR ON ALL TWEB ROUTES...263...273...275 AND 314. KANSAS TWEB
ROUTES FROM KGLD MAY EXPERIENCE AREAS OF IFR AND SOME LOCAL LIFR
CONDITIONS DURING THIS TIME. CONDITIONS SHOULD QUICKLY IMPROVE TO
VFR AFTER 16Z. WIDELY SCATTERED THUNDERSTORMS...A FEW POSSIBLY
SEVERE...ARE POSSIBLE THIS AFTERNOON AND EVENING WITH MVFR
CONDITIONS NEAR THE STORMS. VFR CONDITIONS WILL THEN RESUME WITH
PASSING OF THE STORMS FOR THE REMAINDER OF TUESDAY NIGHT.

.GLD WATCHES/WARNINGS/ADVISORIES...
KS...NONE.
NE...NONE.
CO...NONE.
