Area forecast discussion National Weather Service Bismarck ND 642 am CDT Wednesday Sep 2 2015 Update... issued at 643 am CDT Wednesday Sep 2 2015 Fog forming in parts of central North Dakota. Some patchy areas of dense fog noted at Mandan and Glen Ullin. Have expanded mention of patchy fog until around 9 am CDT when fog should dissipate with the beginning of surface heating for the day. Otherwise current forecast on track. && Short term...(today and tonight) issued at 337 am CDT Wednesday Sep 2 2015 The early morning forecast challenge is fog. Areas of patchy fog are expected to develop across much of central and western North Dakota. Favorable conditions may allow for the development of dense fog in some areas. Fog has begun to develop in the James River Valley and in some south central areas. Otherwise...sunny and warm conditions through the day with highs expected to be well above average. Temperatures will climb into the middle to upper 90s in central and western areas. Seasonal highs for this time of year are around 79 f. Long term...(thursday through tuesday) issued at 337 am CDT Wednesday Sep 2 2015 Continued very warm Thursday...followed by a significant pattern change for the upcoming Holiday weekend. The thermal ridge in place persists into Thursday...but with the approach of the upper level longwave trough on the West Coast a surface low/trough develops and is positioned over the western Dakotas/eastern Montana Thursday morning. This feature moves eastward towards central North Dakota Thursday afternoon. Looking at high temperatures in the middle to upper 90s along and east of the trough...while behind the trough in the northwest expecting temperatures reaching into the 80s. The thermal ridge and attendant surface trough moves east Thursday night...with the first in a series of upper level impulses moving northeast in the southwest flow aloft. Chances of showers and thunderstorms Thursday night from west to east. For the Labor Day weekend: Friday and Saturday the West Coast upper trough begins to move across The Rockies and continue to send a series of shortwave energy impulses across the northern plains. The expected increase in cloud cover and cold advection behind the surface trough/front will result in much cooler weather. Expected highs Friday in the 70s northwest to 80s south central...and highs Saturday mainly in the 70s. Saturday night/Sunday the base of the trough lifts northeastward into the northern plains...reaching southern Canada by Sunday night. This time period (friday-sunday) will see good chances for showers and thunderstorms. Chances of showers and thunderstorms will linger in the north on Monday...with cool conditions. Looking at highs on Labor Day Monday in the middle 60s north to the lower 70s south. The models diverge a bit thereafter...and the forecast consensus is mainly dry with a slow temperature recovery. && Aviation...(for the 12z tafs through 12z Thursday morning) issued at 643 am CDT Wednesday Sep 2 2015 Though areas of patchy fog may linger through 13z...VFR ceilings are expected through the taf period for western and central North Dakota. && Bis watches/warnings/advisories... none. && $$ Update...jv short term...ac long term...jv aviation...ac
