Area forecast discussion National Weather Service Denver/Boulder Colorado 853 PM MDT Thursday may 28 2015 Update... issued at 853 PM MDT Thursday may 28 2015 There have been a couple of rounds of convection that fired behind the main batch of severe storms on the eastern plains...but overall storm intensity and coverage will continue to decrease through the course of the evening as airmass stabilizes. Some weak lift should resume later tonight into Friday morning per latest water vapor imagery and short wave dropping southeast from Wyoming. This will help to bring a few more rain showers back to the high country and northern border area...with snow levels perhaps dropping into the High Mountain valleys by daybreak. Chance of rain will increase behind a weak front early Friday morning...but more widespread showers and a few thunderstorms expected behind a stronger frontal surge by late morning through the afternoon. && Short term...(this evening through friday) issued at 252 PM MDT Thursday may 28 2015 There is pretty good convection going over the plains right now. Hail over an inch has been reported with some of the cells. There are boundaries all over the place. The water vapor pictures are showing another decent batch of convection upstream in eastern Utah and western Colorado...again associated with the approaching trough axis. Models show the weak upper trough axis to push across the County Warning Area this evening and tonight. By Friday afternoon...a weak upper ridge is moving across Colorado. The flow aloft is pretty weak tonight and weak northerly on Friday. Models have a tad of weak upward qg vertical velocity for the northeast quarter of the County Warning Area tonight into Friday morning...then all downward for all the County Warning Area for the first two periods. The boundary layer flow is mainly north and northeasterly tonight and Friday for much of the County Warning Area. Concerning moisture...there is a lot tonight and Friday. The dew points are in the middle 40s to middle 50s f this evening...then mostly the 40s f overnight and Friday. There is some cape around this evening...mostly over the eastern half of the County Warning Area. Values are over 1000 j/kg over the far eastern border areas. There is cape for all the County Warning Area on Friday...but nothing over 1000 j/kg. It will likely not get very warm on Friday with all the cloudiness expected. There is some measurable precipitation over all the County Warning Area most of tonight and Friday too. The greatest amounts are prognosticated this evening over the eastern County Warning Area. Will keep probability of precipitation going overnight...but low after 06z. By late morning Friday will go with "likely"s for much of the County Warning Area. For temperatures...friday's highs look to be 3-7 c cooler than today's. Long term...(friday night through thursday) issued at 252 PM MDT Thursday may 28 2015 Trough will move east of Colorado Friday night. Some disagreement about how fast the clearing/drying will come. NAM continues to be faster suggesting lots of clearing early Monday morning...while the operational GFS remains slowest/wettest and still has significant rain in the foothills Friday evening. Will stick with the idea of a compromise shaded toward the drier solutions...I left the evening probability of precipitation as they were but sped up the departure of the weather by a few hours. This has only minimal probability of precipitation on the southern border and in the mountains early Saturday morning. After that it will be warming and drying aloft and should be too stable for much afternoon convection...though I did leave some low afternoon probability of precipitation in the mountains. Models have trended warmer for Saturday which fits the slightly earlier timing and more sunshine. For Sunday through Tuesday a warm Dry Ridge will move over. There has been a trend toward warmer temperatures which looks alright though I did hold back a few degrees due to the moist ground. We will be near 80 on Sunday which could be the first 80 in may...then low to middle 80s for Monday and Tuesday look good. Models have flipped for the middle to late week trough...but the consensus is the same. Some models show a weak lead trough moving through about Wednesday which would bring a little cooling and perhaps a bit more low level moisture for some increase in thunderstorm activity. Others lack this and would have little change through the end of the week. Main feature is the upstream trough which will keep a warm and mainly dry southwest flow aloft over US. Consensus forecast is fine which shows a little cooling and slight increase in probability of precipitation starting Wednesday...but probably not a big change. && Aviation...(for the tafs through 06z Friday evening) issued at 853 PM MDT Thursday may 28 2015 Thunderstorm threat is shifting to the southeast of the Front Range airports at the present time. Could still see a few rain showers in the overnight hours but main period of showers and a few storms should occur from around 16z Friday to 01z Saturday. Instrument landings expected through that time period due to lower ceilings...as well as possible MVFR conditions in and near showers. Winds should trend light southerly tonight and then to northerly by 12z-16z Friday with passage of cold front. && Hydrology... issued at 853 PM MDT Thursday may 28 2015 Heavy rainfall threat this evening is quickly diminishing as airmass stabilizes. More widespread rainfall is expected Friday...but again it should mainly be light with a low risk of localized flooding and little effect on the larger rivers. The Cache la poudre river in Greeley will remain right near flood stage this weekend...while the South Platte downstream will be slowly falling. By early next week warm temperatures will lead to increasing snowmelt...leading to high flows on rivers and streams in the mountains. This water will progress downstream during the next week so high flows will continue on the South Platte. && Bou watches/warnings/advisories... none. && $$ Update...barjenbruch short term...rjk long term...gimmestad aviation...barjenbruch hydrology...barjenbruch/gimmestad/rjk
