TODAY AND TONIGHT...
A BAND OF SHOWERS IS CURRENTLY DEVELOPING ALONG AND WEST OF HIGHWAY
183. ALOFT, A TROUGH OVER THE ROCKIES IS BEGINNING TO TAKE ON A
NEGATIVE TILT, WITH AN ASSOCIATED SURFACE LOW EMERGING OVER
NORTHEASTERN CO/SOUTHWESTERN NE. THE BAND OF SHOWERS WILL REMAIN
FAIRLY STATIONARY THROUGH AROUND SUNRISE AS IT FILLS IN. AS THE
NEGATIVELY TILTED TROUGH MOVES INTO THE PLAINS, IT WILL STEADILY
SHIFT THE BAND OF SHOWERS EAST ACROSS THE AREA DURING THE MID-LATE
MORNING HOURS. THIS WILL RESULT IN FAIRLY WIDESPREAD RAINFALL ACROSS
THE AREA THIS MORNING/EARLY AFTERNOON, THOUGH ACCUMULATIONS LOOK TO
REMAIN FAIRLY LIGHT WITH THIS ROUND (0.05-0.25 FOR MOST AREAS).
WESTERN PORTIONS OF THE AREA ARE EXPECTED TO SEE AT LEAST SOME
CLEARING BEHIND THE BAND OF SHOWERS. ANY SUNSHINE WILL ALLOW
INSTABILITY TO QUICKLY INCREASE, REACHING 1000-2000 J/KG OF CAPE.
AS A COLD FRONT FROM THE SURFACE LOW PUSHES ITS WAY INTO THE AREA
THIS AFTERNOON, SCATTERED THUNDERSTORM DEVELOPMENT IS EXPECTED ALONG
THE COLD FRONT. CAPE COMBINED WITH SHEAR OF 25-30KTS WILL RESULT IN
AN ENVIRONMENT SUPPORTIVE OF STRONG-SEVERE THUNDERSTORMS CAPABLE OF
PRODUCING LARGE HAIL AND DAMAGING WIND GUSTS. THUNDERSTORMS ARE
LIKELY TO FORM INTO ONE OR MORE CLUSTERS AS THEY MOVE EAST INTO
CENTRAL/EASTERN PORTIONS OF THE AREA THIS EVENING. INSTABILITY WILL
QUICKLY DROP OFF AROUND SUNSET RESULTING IN THUNDERSTORMS DECREASING
IN INTENSITY. ANY LINGERING SHOWER/STORM WILL EXIT EASTERN PORTIONS
OF THE AREA SHORTLY AFTER MIDNIGHT.
MONDAY...
WEST-SOUTHWESTERLY FLOW WILL REDEVELOP OVER THE AREA ON MONDAY, AS A
SHORTWAVE TROUGH MOVES INTO THE ROCKIES. HIGHS IN THE 80S ARE
EXPECTED ON MONDAY WITH SOUTHERLY WINDS GUSTING 15-20MPH AND MOSTLY
SUNNY SKIES. LOWS MONDAY NIGHT WILL BE IN THE 60S.
TUESDAY...
A COLD FRONT SINKS INTO THE AREA ON TUESDAY AHEAD OF AN APPROACHING
SHORTWAVE TROUGH. THE COLD FRONT WILL STRETCH FROM CENTRAL SOUTH
DAKOTA TO NORTHEASTERN COLORADO TUESDAY AFTERNOON. SOUTH OF THE COLD
FRONT, HIGHS IN THE 80S ARE EXPECTED. SCATTERED THUNDERSTORMS WILL
DEVELOP ALONG THE COLD FRONT DURING THE AFTERNOON. A FEW STRONG-
SEVERE STORMS ARE POSSIBLE GIVEN FAVORABLE CAPE AND SUFFICIENT
SHEAR, THOUGH THE EXTENT OF SEVERE POTENTIAL REMAINS UNCERTAIN
AT THIS TIME. STORMS MOVE SOUTHEAST ACROSS THE AREA TUESDAY
EVENING/NIGHT, BRINGING ANOTHER CHANCE (40-75%) FOR WIDESPREAD
PRECIPITATION TO THE AREA.
WEDNESDAY ONWARDS...
TROUGHING OVER THE ROCKIES WILL BECOME SOMEWHAT CUT OFF FROM THE
BROADER FLOW ALOFT ON WEDNESDAY, WITH AN UPPER LEVEL LOW SLOWLY
MOVING ACROSS THE AREA THROUGH THE LATTER HALF OF THE FORECAST
PERIOD. MULTIPLE WAVES OF ENERGY WITHIN THIS LOW WILL BRING
SCATTERED CHANCES (30-60%) FOR STORMS TO THE AREA EACH DAY. BELOW
NORMAL TEMPERATURES ARE EXPECTED WEDNESDAY ONWARDS WITH HIGHS IN THE
70S.

MID- UPPER LEVEL CLOUD COVER DEPARTS, SEEING LOWER LEVEL CU
DEVELOPING IN ITS WAKE...AND THAT WILL BE POSSIBLE FOR THE
