AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BISMARCK ND
321 PM CDT FRI JUL 19 2013

.SHORT TERM...(THIS EVENING THROUGH SATURDAY)
ISSUED AT 306 PM CDT FRI JUL 19 2013

SHORT TERM CONCERNS INVOLVE THUNDERSTORMS NORTH CENTRAL ASSOCIATED
WITH A CANADIAN COLD FRONT SLIDING SOUTH ACROSS THE REGION. CAPE
VALUES SHOW POTENTIAL FOR STRONG THUNDERSTORMS BUT MID LEVEL LAPSE
RATES AROUND 5 TO 6 DEGREES SHOULD LIMIT THE SEVERE POTENTIAL.
HOWEVER THE POTENTIAL FOR SOME HAIL AND GUSTY WINDS EXISTS THIS
EVENING. EXPECT SOME DIURNAL MINIMUM TONIGHT FOR THE STORMS...AND
SCATTERED THUNDERSTORMS ALONG THE FRONTAL ZONE SOUTH CENTRAL AND
WEST SATURDAY.

 .LONG TERM...(SATURDAY NIGHT THROUGH FRIDAY)
ISSUED AT 306 PM CDT FRI JUL 19 2013

H5 PATTERN PER GFS/ECMWF CONTINUES WITH MOSTLY A NORTHWEST FLOW
ALOFT THROUGH THE PERIOD. PERIODIC UPPER DISTURBANCES IN COMBINATION
WITH INSTABILITY AND DYNAMICAL PARAMETERS IN PLACE WILL ALLOW FOR A
CHANCE OF SHOWERS AND/OR THUNDERSTORMS ALMOST EVERYDAY...WITH THE
EXCEPTION OF MONDAY...WHERE A DRY DAY IS FORECAST.

FOR SATURDAY NIGHT AND SUNDAY...MAIN HIGHLIGHT HERE IS A MORE
SIGNIFICANT SHORTWAVE MOVING THROUGH SOUTHERN SASKATCHEWAN SUNDAY
MORNING AND INTO SOUTHERN MANITOBA BY SUNDAY AFTERNOON. A SURFACE
COLD FRONT WILL BE ASSOCIATED WITH THE SHORTWAVE ALOFT AS IT SLIDES
FROM WEST TO EAST SUNDAY AFTERNOON AND EVENING. BEST FORCING/OMEGA
RESIDES IN THE NORTH CENTRAL SUNDAY AFTERNOON THEN SHIFTS INTO EAST
CENTRAL NORTH DAKOTA SUNDAY EVENING. VERTICAL MOTION IS ENHANCED BY
THE LEFT EXIT REGION OF A 60KT H3 JET STREAK ACROSS THE
AFOREMENTIONED AREA. GFS SHOWS ENOUGH CAPE AND 0-6KM SHEAR OF 45KT
TO 50KT FOR ORGANIZED STORMS WHICH WILL FAVOR SOME SEVERE
THUNDERSTORMS NORTH CENTRAL THROUGH EAST CENTRAL SUNDAY AFTERNOON
THROUGH SUNDAY EVENING. SPC DAY 3 OUTLOOK HAS THE ABOVE AREA IN A
SEE TEXT WITH HAIL AND WIND AS THE PRIMARY THREATS. H85 TEMPS RISE
TO BETWEEN +26C TO +28C IN THE WARM SECTOR SUNDAY AFTERNOON WEST PER
NAM/GFS...HIGHS WILL TOP OUT AROUND 90 OR LOWER 90S. HAVE INCREASED
TEMPS TO REFLECT THIS...HOWEVER DID NOT GO AS WARM AS THE NAM MOS
WANTED DUE TO SOME CLOUD COVER HOLDING TEMPS BACK IN THE MORNING TO
EARLY AFTERNOON. SHOULD BE A QUICK RISE THEREAFTER.

MONDAY...BEHIND THE COLD FRONT...GFS SOUNDINGS SHOW LOW LEVEL COLD
AIR ADVECTION WITH NEUTRAL ADVECTION ALOFT WILL YIELD A COOLER/DRIER
DAY WITH HIGHS IN THE UPPER 70S NORTH TO UPPER 80S SOUTH.

FOR TUESDAY THROUGH FRIDAY...ADDITIONAL SHORTWAVES EMBEDDED IN THE
NORTHWEST FLOW WILL INTERACT WITH THE AFTERNOON/EVENING INSTABILITY
AND SOME JET FORCING AT TIMES TO INITIATE A CHANCE OF
SHOWERS/THUNDERSTORMS.

&&

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z SATURDAY AFTERNOON)
ISSUED AT 306 PM CDT FRI JUL 19 2013

AT 3 PM CDT...VFR CONDITIONS ARE OBSERVED AND ARE FORECAST
THROUGH THE 18Z TAF PERIOD. A WEAK COLD FRONTAL BOUNDARY ACROSS
SOUTHERN CANADA WILL BE THE FOCUS FOR THUNDERSTORMS ACROSS
NORTHERN NORTH DAKOTA AFTER 21Z...AND ACROSS THE SOUTH AFTER 00Z.
THUNDERSTORMS SHOULD BE SCATTERED TO ISOLATED. PLAN TO CONTINUE
TO EXPRESS THE THUNDERSTORM HAZARD VIA VCTS (VICINITY).

.BIS WATCHES/WARNINGS/ADVISORIES...
