AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AMARILLO TX
417 PM CDT WED MAY 4 2016

.SHORT TERM...TODAY THROUGH FRIDAY...
LIGHT WINDS...WARMER TEMPS...AND CLEAR BLUE SKIES MARK THE ARRIVAL OF
THE UPPER LEVEL RIDGE OF HIGH PRESSURE TODAY. EXPECT WARMING TREND TO
CONTINUE THROUGH THE END OF THIS WEEK AS THE RIDGE SHIFTS EASTWARD.
BREEZY SOUTHERLY WINDS EXPECTED BY FRIDAY AFTERNOON IN RESPONSE TO A
DEVELOPING SURFACE LOW OVER SOUTHEASTERN COLORADO. LOOKS LIKE THE
ATMOSPHERE SHOULD BE TOO DRY TO SEE TRUE RAIN SHOWERS ON FRIDAY
NIGHT...BUT CANNOT RULE OUT AN ISOLATED SHOWER OR STORM PRODUCING
GUSTY WINDS FRIDAY NIGHT IN THE WESTERN COUNTIES.

.LONG TERM...SATURDAY THROUGH WEDNESDAY...
ATTENTION IN THE LONGER TERM FORECAST REMAINS ON THE POTENTIAL FOR
THUNDERSTORMS SATURDAY NIGHT THROUGH SUNDAY NIGHT. STILL SOME
UNCERTAINTY BETWEEN MODELS REGARDING THE AVAILABILITY OF LOW-LEVEL
MOISTURE...PLACEMENT OF THE DRYLINE...AND SUBSEQUENT STORM
DEVELOPMENT ACROSS THE PANHANDLES. GIVEN THE BIAS IN THE GFS TOWARD A
DRIER LOWER ATMOSPHERE...LARGELY LEANED TOWARD THE ECMWF FOR MOISTURE
RELATED FIELDS. THAT SAID...THE ECMWF HAS COME IN WITH A LITTLE
FARTHER EAST DRYLINE POSITION FOR SATURDAY AFTERNOON/EVENING...AND
LATEST SUITE OF MODEL GUIDANCE SUGGEST A MORE DYNAMIC PUSH TO THE
DRYLINE ON SATURDAY AS WELL. IT NOW APPEARS THAT THE PACIFIC COLD
FRONT MAY REACH THE PANHANDLES BY SATURDAY EVENING...HELPING TO KEEP
MOIST AIR LIMITED TO THE EASTERN PANHANDLES OVERNIGHT. VALUES OF
MLCAPE NEAR 1000 TO 1500 J/KG WOULD BE POSSIBLE ALONG THE DRYLINE
SATURDAY NIGHT...AND AGAIN ON SUNDAY. 100KT JET EDGING INTO THE
PANHANDLES WILL PRODUCE 0-6KM SHEAR OF 40-60 KTS ACROSS THE AREA ON
BOTH DAYS. THE DRYLINE SHOULD BE MOST OF THE WAY THROUGH THE EASTERN
PANHANDLES SUNDAY EVENING THANKS TO INCREASED UPPER-LEVEL SUPPORT
FROM THE APPROACHING CLOSED LOW. MINOR ADJUSTMENTS HAVE BEEN MADE TO
POPS TO ACCOUNT FOR THIS. FINALLY...THE CLOSED UPPER LOW FILLS AND
LIFTS NORTHEASTWARD MONDAY AND PUSHES A COLD FRONT THROUGH THE AREA
/THOUGH NO SIGNIFICANTLY COOLER AIR BEHIND IT/. IN ITS
WAKE...NORTHWEST FLOW DEVELOPS ALOFT AS A NORTHERN STREAM SHORTWAVE
DIGS INTO THE NORTHERN ROCKIES FOR EARLY NEXT WEEK. CANNOT RULE OUT A
CHANCE FOR PRECIP SOMEWHERE ACROSS THE AREA BY THE MIDDLE OF NEXT
WEEK.
