Area forecast discussion National Weather Service Denver/Boulder Colorado 1041 am MDT Tuesday Oct 6 2015 Update... issued at 1041 am MDT Tuesday Oct 6 2015 Fog is slowly lifting but conditions have improved enough to allow expiration of dense fog advisory on the eastern plains. Next concern surrounds convection. There are already a few showers developing above the stable boundary layer and these will continue through the noon hour. By early afternoon...surface based convection will become widespread over the mountains and foothills where due to stronger daytime heating where more sunshine has occurred this morning. These showers and storms are expected to push northeast across the plains later in the afternoon and evening as upper level divergence increases in left exit region of the jet rounding the base of the Desert Southwest cutoff low. The idea of high probability of precipitation for this period looks good. Any severe threat is limited by the lack of sufficient heating and destabilization on the plains. However...stronger storms will still produce brief heavy rain and small hail. Main forecast changes were to delay clearing of the stratus on the plains and slightly cooler temperatures. Update issued at 707 am MDT Tuesday Oct 6 2015 Widespread fog had developed on the plains and web cams/metars show sufficient coverage of 1/4 mile visibility for a dense fog advisory. There is not much cloud cover above the stratus deck and its fairly thin so visibilities will improve between 9 and 10 am. && Short term...(today through tonight ) issued at 400 am MDT Tuesday Oct 6 2015 A moist southwesterly flow aloft will stream over the region through tonight...ahead of an upper level low pressure system currently over Southern California. This system is expected to track slowly eastward...moving into west central Arizona by 00z Wednesday then into east central Arizona by 12z Wednesday morning. Over Colorado a moist diffluent flow aloft will be impacting the region... especially this afternoon and evening. The forecast soundings from the nam12/GFS buffer data indicate 300-500 j/kg of cape this afternoon. In addition...there is an 80 knots jet rounding the trough today and it expected to nose its way into southern Colorado. As a result the combination of some jet dynamics aloft coupled with the instability should produce a good support of widespread showers along with some embedded thunderstorms. It should be too warm for snow showers in the high country today...but cool enough tonight for some light snowfall above 12k feet...so will keep the mention of 1 to 3 inches in the grids. The hrrr/RUC start to develop some showers from Denver east and south this morning...so will mention rainfall early. A surface low is prognosticated to form over southeastern Colorado this morning with the surface winds shifting from northeasterly to north-northwesterly later today. Light winds and lingering low level moisture early this morning has resulted in more fog from Denver east and northeast...so will add patchy coverage through 15z. It could be dense in spots with visibility less than one half mile. Plenty of cloud cover today as well will limit heating so have trimmed the probability of precipitation back by a couple of degrees. Long term...(wednesday through monday) issued at 400 am MDT Tuesday Oct 6 2015 The closed upper low over Southern California at the moment the will continue its lumbering southeasterly trek across Arizona during the day Wednesday. Then models show it making a sharp right turn into northern Mexico by early on Thursday. Due to the slow progression of this system...Wednesday will remain relatively cool and unsettled. Particularly during the morning hours due in part to the passage of a weak pertabation at mid-levels. For that reason will keep a chance of showers mainly in the mountains Wednesday morning and as drier air moves down from Wyoming during the afternoon...decrease precipitation chances from north to south. Cannot rule out a stray T-storm but limit instability due to lingering cloud cover should pretty much confine any thunder to marginally warmer southeastern sections of the County Warning Area. Clearing will continue overnight as the upper low continues to move away and with subsident side of the speed maxima passing over the area. Near average temperatures expected Wednesday and Wednesday night. On Thursday...strong upper level ridging over the West Coast causes flow aloft to veer more northwesterly over the Rocky Mountain region. This flow drives a weak cold front south out of Wyoming and across northeast Colorado during the day bringing with it another batch of clouds and cooler air. Mostly cloudy skies are expected on Thursday along with a slight chance of showers both mountains and plains. Post frontal northeasterly flow may concentrate most of this shower activity to the east slopes of the Front Range west and southwest of Denver. However precipitation amounts will be minimal. Temperatures on Thursday are forecast to be 4-6 degree f lower than the day before. See no reason to argue with that. Looking ahead to the period Friday-Sunday...the big upper ridge building out west is prognosticated to migrate east during the period... with its apex reaching Colorado this weekend. This will result dry conditions and above average temperatures areawide. On the plains...high temperatures are expected to Hoover around the 80 degree mark both days. && Aviation...(for the tafs through 18z Wednesday morning) issued at 1041 am MDT Tuesday Oct 6 2015 Visibility slowly improving and will continue to do so through 18z-19z. Stratus breakout program showed a very slow erosion today...but with convective clouds developing quickly to our south and spreading north expect enough mixing for lower clouds to break up through the early afternoon hours. Showers and storms will form shortly thereafter and become more widespread through late afternoon and evening. Feel enough instability to our southwest to warrant tempo thunder for a few hours...highest probability 22z- 04z. There is some fog threat again overnight as boundary layer moisture may now scour eastward. && Bou watches/warnings/advisories... none. && $$ Update...barjenbruch short term...Cooper long term...Baker aviation...barjenbruch
