SOUTH CENTRAL NEBRASKA/NORTH CENTRAL KANSAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
150 PM CDT WED JUL 18 2001

MAIN CONCERN IS THUNDER POTENTIAL TONIGHT AND THE CONTINUING HEAT.

REGIONAL RADAR MOSAIC THIS AFTERNOON CONTINUES TO SHOW WDLY
SCATTERED SHOWERS AND THUNDERSTORMS MAINTAINING THEMSELVES IN AREA
OF STRONG INSTABILITY AND MID LEVEL WAA LIFT...MOSTLY SOUTH OF I-
80. STORMS ARE INTENSIFYING AS THEY MOVE EAST INTO RICHER MOISTURE.
MEANWHILE...WATER VAPOR IMAGERY CONTINUES TO SHOW THE NON-
PROGRESSIVE PATTERN OF THE UPPER LEVEL HIGH PRESSURE DOME OVER THE
CENTRAL STATES WITH ACCOMPANYING TROFS ON EITHER SIDE. THE MAIN
UPPER LEVEL LOW OVER ALBERTA  CONTINUES TO EJECT A SERIES OF VORTS
OUT OF THE GREAT BASIN AND INTO THE NORTHERN PLAINS. AT THE SAME
TIME AMPLE MOISTURE CONTINUES TO STREAM NORTHEASTWARD OUT OF THE SUB-
TROPICS REGION. AT THE SFC...LOW PRESSURE WAS SITUATED OVER SD WITH
A STALLED BOUNDARY CUTTING THROUGH THE NORTHERN PLAINS INTO THE
OHIO VALLEY...AND TO THE EAST COAST. A COOL FRONTAL BOUNDARY WAS
APPARENT EAST OF THE NORTHERN ROCKIES IN EASTERN MT/WY.

THE ETA IS SUGGESTING THAT THE DEVELOPMENT OF A CONVECTIVE COMPLEX
IS PLAUSIBLE THIS EVENING OVER NORTHERN SECTIONS OF NEB. LOW LEVEL
GEOSTROPHIC WINDS TAKE A CYCLONIC TURN WITHIN A SMALL AREA OF 850MB
FRONTOGENESIS BETWEEN 00Z & 06Z IN THE VICINITY OF VTN...
SUGGESTING INITIATION CLOSE TO THAT LOCATION. AS STORMS ORGANIZE
OVERNIGHT WITH THE STRENGTHENING OF THE LOW LEVEL JET...CORFIDI
VECTORS INDICATE MOVEMENT EAST THEN SOUTHEAST. AT THIS POINT...AM
INCLINED TO GO WITH SMALL POPS...30 OR 40% CAUSE I'M NOT SURE IF
STORMS WILL BREACH NORTHERN CWA.

OTHERWISE...THE HEAT AND HUMIDITY SAGA CONTINUES. TEMPS TONIGHT
PROBABLY WON'T JUSTIFY AN ADVISORY...BUT ONE WILL MOST LIKELY BE
NEEDED TOMORROW AND FRIDAY AS LOW LEVEL MOISTURE CONTINUES TO SHOOT
NORTHWARD AND THE UNPROGRESSIVE UPPER LEVEL HIGH REMAINS IN PLACE.

NO MAJOR CHANGES TO THE EXTENDED.

.GID...NONE.
