Area Forecast Discussion National Weather Service Denver/Boulder CO 233 PM MDT Tue Apr 12 2022 .SHORT TERM...(This afternoon through Wednesday) Issued at 215 PM MDT Tue Apr 12 2022 Front has cleared the forecast area as of early afternoon. Temperatures behind the front have dropped into the 40s and 50s on th eplains, and below freezing in the mountains and foothills. Strongest wind this morning was in southwest flow ahead of the front, although still gusting to 30-40 mph from NW. Will leave the Red Flag Warning and High Wind Warning in effect for this afternoon. Still believe there is a chance for the shallow frontal layer to mix out across the Palmer Ridge, bringing those strong 500 mb winds down to the surface along with some drying of dewpoints. Overnight tonight a trough axis rotating around the upper low to the north will swing across the area. A weak area of QG lift along with remaining SW orographic flow will enhance precip chances, peaking around 12z, before tapering off during the day tomorrow. For Wednesday upper low departs, with continued westerly flow at the surface. Light wind overnight tonight into early morning Wednesday will yield to renewed westerly downslope flow with gusts to 30 mph on the plains. Dry RH and wind in southern Lincoln & Elbert county will prompt upgrading of the Fire Weather Watch to Red Flag Warning with this forecast cycle. RH will drop to 15-20 percent adjacent to the foothills, Wednesday afternoon as well, however not widespread and will let it go another forecast cycle for decision. Cool day on tap for Wednesday, with highs only 35-45 on the plains and 20s mountains, which is good for 15 degrees below normal plains and 20 to 25 degrees below normal in the mountains. .LONG TERM...(Wednesday night through Tuesday) Issued at 215 PM MDT Tue Apr 12 2022 ...PROGRESSIVE WEATHER PATTERN THROUGH EARLY NEXT WEEK WITH BOUTS OF WIND AND SOME MOUNTAIN SNOW... Mid level moisture will thin out Wednesday night with clearing skies expected, while winds diminish in the evening as weak inversions develop. Light snow showers lingering in the high country will also slowly diminish, but another inch or two expected in some spots with favored orographics in west/northwest flow aloft. Low temperatures will once again be quite cold with readings dropping into the mid teens to lower 20s across the plains, and single digits in most of the high country despite some orographic cloud cover. Thursday will see a start of a warmup slight upper level ridging and warm advection. However, temperatures will still be several degrees below normal. We expect another breezy/windy day and lower humidity across the plains which will once again lead to more fire weather concerns. Mountain areas may see another round of light snow showers with sufficient mid level moisture in the weak warm advection pattern, but overall these patterns aren't very favorable for much snow. A weak short wave passing just to our north could bring a little enhancement Thursday night or early Friday morning, but there's a fair amount of uncertainty here. The warmup could be delayed if a cold front/short wave do push through. Saturday has potential to be the warmest day with flat upper level ridging. Unfortunately this would also lead to continued dry weather and critical fire weather conditions. Another fast moving wave could bring some snow back to the mountains by Saturday night or Sunday, but in these fast moving/progressive weather patterns timing is somewhat uncertain. Overall, it looks like a fairly dry and windy at times weather pattern will remain in place across the plains through at least early next week, keeping fire weather at the forefront of our main weather concerns. && .AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon) Issued at 1136 AM MDT Tue Apr 12 2022 Wind out of the west to northwest through the forecast period with VFR cigs/vis. Potential for gusts up to 30 kts through this afternoon as mid atmospheric flow mixes down to the surface. Speeds diminish this evening, and while KDEN remains west to NW direction, KAPA/KBJC will become variable. Windspeeds to increase again Wednesday after 15z, gusting to 30 kts again. && .FIRE WEATHER... Issued at 215 PM MDT Tue Apr 12 2022 Red flag warning remains in effect this afternoon for Palmer divide and Lincoln county. Surface observations showing cold front has mixed out in southern Elbert County, with temperatures jumping back into the lower 50s and dewpoints dropping to mid 20s. Expect this to continue and spread further east into Lincoln County, and worth continuing RFW there. Overnight tonight winds die off with colder temperatures driving RH recovery. For Wednesday, although cooler, also drier Wednesday afternoon in southern Lincoln county and will upgrade Fire Weather Watch to Red Flag Warning for fire zone 247.Elsewhere elevated fire weather conditions with dry conditions and breezey winds. Of note areas adjacent to the foothills where downslope winds will lower RH to 15-20 percent Monday afternoon, but conditions marginal for an RFW there. Widespread elevated and locally critical fire weather conditions are likely to continue into early next week. There may be a weak cold front passage Friday or into early Saturday which would lead to a little respite from the almost daily fire weather concerns. && .BOU WATCHES/WARNINGS/ADVISORIES...
