.DISCUSSION...
SHWRS AND TSTMS HAVE BEEN INCREASING ACROSS PORTIONS OF CENTRAL
NEBRASKA EARLY THIS MORNING. THIS INCREASE IS LIKELY TIED TO THE
WEAK WAA NOTED AROUND 700MB AHEAD OF A DISTURBANCE ADVANCING EAST
ACROSS WESTERN NEBRASKA. ACTIVITY IS SCATTERED IN NATURE...AND WILL
WORD AS SUCH IN THE FORECAST DURING THE MORNING HOURS ACROSS CENTRAL
AND SOUTHERN POTIONS OF EASTERN NEBRASKA AND SOUTHWEST IOWA. LATER
THIS AFTERNOON...IT APPEARS ISOLATED TO SCATTERED TSTMS WILL
INITIATE ALONG A SECONDARY COLD FRONT ENTERING THE WESTERN PORTIONS
OF NORTHEAST NEBRASKA DURING THE LATE AFTERNOON. THESE STORMS WILL
THEN PUSH SOUTHEAST...REMAINING IN AN ISOLATED TO SCATTERED
FASHION...ACROSS EASTERN NEBRASKA AND WESTERN IOWA THROUGH THE
EVENING. A COUPLE OF THESE COULD BECOME SEVERE AS SHEAR AND
INSTABILITY WILL BE ADEQUATE...BUT WIDESPREAD SEVERE WEATHER IS NOT
EXPECTED. ANY REMAINING ACTIVITY WILL PUSH SOUTHEAST OF THE AREA BY
MIDNIGHT...WITH DRY WEATHER EXPECTED TUESDAY WITH NO REAL FOCUS FOR
CONVECTIVE DEVELOPMENT. TUESDAY NIGHT AND WEDNESDAY A RATHER STRONG
SHORTWAVE DISTURBANCE WILL TRANSLATE EASTWARD FROM WYOMING THROUGH
NEBRASKA. SHWRS AND TSTMS WILL LIKELY ACCOMPANY THIS DISTURBANCE
ACROSS WESTERN AND CENTRAL NEBRASKA...WITH SOME OF THIS ACTIVITY
MAKING IT INTO EASTERN NEBRASKA AFTER MIDNIGHT TUESDAY NIGHT AND
CONTINUING WEDNESDAY. THE NEXT BEST CHANCE FOR SHWRS/TSTMS WILL COME
WITH A COLD FRONTAL PASSAGE THURSDAY NIGHT. MAINLY DRY CONDITIONS
ARE THEN EXPECTED IN THE WAKE OF THE COLD FRONT THROUGH THE WEEKEND.
WEAK HIGH PRESSURE WILL NOSE INTO EASTERN NEB AND SOUTHWEST IOWA
MONDAY NIGHT INTO TUESDAY...BRINGING COMFORTABLE TEMPS AND
LOWERING HUMIDITY LEVELS. IN FACT LOWS BY WEDNESDAY MORNING ARE
EXPECTED TO SETTLE IN THE MID TO UPPER 50S ACROSS NORTHEAST
NEBRASKA WITH LOWER 60S SOUTHEAST. ALL IN ALL TEMPS THROUGH THE
WEEK WILL BE QUITE PLEASANT...WITH HIGHS IN THE UPPER 70S TO MID
80S.
