.SHORT TERM...(TODAY THROUGH TUESDAY)
ISSUED AT 313 AM CDT MON JUL 28 2014

THE CHALLENGE FOR THIS NIGHT SHIFT WILL BE STAYING AWAKE AS THE
PATTERN TAKES A TURN TOWARDS THE BORING.

WV LOOP AND UPPER AIR ANALYSIS HAVE NORTHWESTERLY FLOW ALOFT
CONTINUING OVER THE NORTHERN PLAINS AS THE RIDGING IN THE WESTERN
CONUS AND TROUGH IN THE EAST SETS UP FOR THE NEXT FEW DAYS. HIGH
PRESSURE AT THE SFC WILL BRING CLEARING SKIES TODAY AND NORTH
WINDS NOT AS STRONG AS THE PAST FEW DAYS. THE NAM PERSISTS IN
BRINGING A WEAK SHORTWAVE TROUGH DOWN INTO NORTHERN MN WITH PRECIP
CLIPPING THE LAKE OF THE WOOD AREA. HOWEVER...IT SEEMS TO BE AN
OUTLIER WITH HOW FAR WEST SHOWERS DEVELOP. WILL CONTINUE TO KEEP
THE FORECAST DRY FOR NOW. THINK WE SHOULD SEE MORE SUNSHINE
TODAY...WHICH SHOULD HELP TEMPS CLIMB INTO THE 70S.

NORTHWESTERLY FLOW ALOFT AND HIGH PRESSURE WILL CONTINUE THROUGH
TONIGHT AND TUESDAY. WINDS WILL BECOME LIGHT UNDER THE SFC HIGH
CENTER OVER CENTRAL ND OVERNIGHT...SO WILL HAVE TO WATCH THE
WESTERN COUNTIES FOR ANY PATCHY FOG FORMATION OVERNIGHT BUT
CHANCES ARE LOW ENOUGH AT THIS POINT TO NOT INCLUDE IN THE GRIDS.
LOWS SHOULD DROP DOWN INTO THE 50S AGAIN TONIGHT AND HIGHS ON
TUESDAY WILL BE A FEW DEGREES WARMER THAN TODAY AND TOP OUT IN THE
UPPER 70S.

.LONG TERM...(TUESDAY NIGHT THROUGH SUNDAY)
ISSUED AT 313 AM CDT MON JUL 28 2014

TUESDAY NIGHT THROUGH WEDNESDAY NIGHT...THE VERY QUIET PATTERN
CONTINUES WITH NORTHWESTERLY FLOW ALOFT AND SFC HIGH PRESSURE.
NOT MUCH AIR MASS CHANGE BUT WITH A BIT MORE WIND OVERNIGHT TEMPS
SHOULD STAY IN THE MID TO UPPER 50S FOR BOTH NIGHTS. HIGHS ON
WEDNESDAY SHOULD GET TO NEAR SEASONAL AVERAGES IN THE UPPER 70S TO
LOW 80S.

THURSDAY TO MONDAY...MODELS IN EXCELLENT AGREEMENT WITH 500MB NW
FLOW ALOFT WITH THE NORTHERN PLAINS UNDER PREDOMINANTLY HIGH
PRESSURE AND THUS DRY WEATHER. TEMPS WILL BE NEAR NORMAL WITH
INCREASING HEIGHTS AND DEWPOINTS AS WESTERN RIDGE SLOWLY PUSHES INTO
THE FA BY THE WEEKEND. KEPT THE ISO POCKETS OF CHC FOR THUNDER AS
A RIDGE RIDER COULD BRING PCPN TO THE FA.

&&

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z TUESDAY AFTERNOON)
ISSUED AT 1226 PM CDT MON JUL 28 2014

STILL HAVE A PERSISTENT 6000FT CLOUD DECK OVER THE SOUTHERN RED
RIVER VALLEY. THINKING IT SHOULD BE GONE IN THE NEXT HOUR BUT IT
WILL BE REPLACED BY OTHER CUMULUS. SKIES SHOULD CLEAR THIS EVENING
WITH MORE CUMULUS AROUND LATER TUE MORNING. LOOKING AT STEADY NW
WINDS AT 5 TO 10 KNOTS EXCEPT CALM IN THE EVENING AND OVERNIGHT.
