NWS Denver/Boulder, CO wrote its last area forecast discussion before the first event at May 30, 9:53 AM MST, 3 hours 25 minutes earlier.
Area Forecast Discussion National Weather Service Denver/Boulder CO 1053 AM MDT MON MAY 30 2016 .UPDATE... Issued at 1053 AM MDT Mon May 30 2016 No need for any changes to the forecast at this time. Satellite imagery shows a short wave over northwest Colorado at the present time that will be moving out over the northeast plains during the afternoon hours. We should start seeing showers develop over the mountains in the next hour or so. Model soundings are showing around 1000-2000 j/kg of CAPE this afternoon, with higher values further to the east. With the higher CAPE values on the far eastern plains, the strongest storms will develop out there, later in the evening. && .SHORT TERM...(Today and tonight) Issued at 403 AM MDT Mon May 30 2016 The forecast area is in between weak short waves at the present time with mostly clear skies in place. However, the next short wave moving across Utah will arrive by this afternoon with increasing clouds and convection. Q-G fields show only slight if any lift, and most of that skirting by to our North and South. Nonetheless, satellite data would suggest at least an increase in mid level moisture so the higher PoPs in the forecast for today seem reasonable. Should see scattered shower and thunderstorm coverage develop first in the mountains by late morning and then spread/develop east across the plains shortly after noon. Low level moisture appears rather thin early this morning, so CAPE will likely erode along the Front Range to around 500 J/kg, while farther east on the plains toward Sterling, Akron, and Limon CAPE should hold closer to 1000 to perhaps 1500 J/kg keeping potential for one or two severe storms there. SPC outlook seems to depict this potential well. Strong gusty winds will be the main threat due to relatively high based storms and increasing mid level wind field, along with isolated large hail reports possible in areas of higher CAPE. For tonight, cold front will push south across the plains late this evening. Behind that, shallow and moist upslope regime should result in areas of stratus along with patchy drizzle or light showers, and areas of fog where stratus deck runs into the ground - namely the foothills. .LONG TERM...(Tuesday through Sunday) Issued at 403 AM MDT Mon May 30 2016 Upper level trough dropping in from the northwest and moist post-frontal anticyclonic upslope flow on the plains promises a cooler...cloudy and wet day Tuesday esply for areas east of the Continental Divide. Upslope flow on the plains is progged to be relatively shallow during the day...generally no more than 7000-8000 ft at its greatest depth Tuesday morning. Models show this shallow upslope flow becoming nearly saturated up against the Front Range during the morning hours. Without much forcing aloft or instability...the heavy deck of low clouds pushed up against the Front Range will probably produce not much more than light rain and/or drizzle...and even areas of fog during the morning hours. The fog should be concentrated in the foothills where visibilities may lower below a mile at times during the morning. Farther out on the plains the low cloud cover will not as thick nor as extensive and the chance of precip not as great. High country areas generally west of the Continental Divide should see less cloud cover and warmer temperatures on Tuesday...and with more sunshine a slight chance of t-storms by afternoon. Highs on the plains expected to be only in the 60s. Tuesday night and Wednesday...the upper trough shifts east by nighttime placing the forecast area under northwest flow aloft. Models show a weak mid-level disturbance embedded in this flow passing over the CWA during the evening hours. Could see some enhancement in shower activity including a few t-storms as a result. After midnight should see drier air spreading down from Wyoming resulting in gradual clearing from north-to-south by early Wednesday morning. During the day Wednesday...low-level flow on the plains turns sely as per models which could lead to isolated shower/t-storm development over and near the Front Range and across South Park by early to mid-afternoon. Temps on Wednesday should be a few degs warmer with the return of sunshine. Thursday through Sunday...the upper ridge building over the Great Plains will slowly migrate eastward during the period bringing warmer temperatures and drier air to the forecast area. The chance of t-storms should significantly drop off as daytime temperatures climb several degs above average. Temperature guidance gives highs in the low to mid-80s for the plains. Can't see any reason to go against that. && .AVIATION...(For the 18Z TAFS through 18Z Tuesday afternoon) Issued at 1053 AM MDT Mon May 30 2016 Will hold onto the forecast of a round of thunderstorms moving across the Denver area late this afternoon. With a weak upper level disturbance moving across the area this afternoon, it will be difficult for thunderstorms to not develop. The storms will be high-based after moving off the foothills. Gusty winds and brief rain will be the main threats at the airports. && .BOU Watches/Warnings/Advisories... None. && UPDATE...Dankers SHORT TERM...Barjenbruch LONG TERM...Baker AVIATION...Dankers
