Area forecast discussion, Jul 2, 4:14 PM MST, 2 hours 11 minutes before
Area Forecast Discussion National Weather Service Cheyenne WY 514 PM MDT Fri Jul 2 2021 .SHORT TERM...(This evening through Monday night) Issued at 212 PM MDT Fri Jul 2 2021 Forecast concerns deal with shower/thunderstorm chances through the short term. Currently...still have a stationary boundary over the eastern half of our CWFA this afternoon. Dewpoints in the upper 50s east of this front across the Nebraska Panhandle and low 50s across the southeast Wyoming plains east of the Laramie Range. While west of the front...we are seeing upper 30s and low 40s across Carbon County. Radar beginning to show some showers and thunderstorms developing across northern Colorado. For this afternoon...looking at afternoon surface based CAPE on the order of 1500/2000 J/KG with afternoon heating. Sfc-6km shear still not all that impressive around 20-30kts. So not expecting much in the way of severe thunderstorms. Forecast storm motions still low...under 15kts...especially out in the panhandle. So could see some heavy rainers once again today. Latest HRRR shows convection peaking out around 22Z to 01Z...then dying off quickly with less heating. SPC has a Marginal Risk for severe thunderstorms in the Nebraska Panhandle for Saturday. A little bit better directional shear as upper level winds out of the northwest and low level winds out of the southeast. Still not all that impressive...but a few storms could be severe Saturday afternoon. Clipper system Sunday moves through the eastern CWFA that could give us another good chance for more widespread convection into Monday afternoon. .LONG TERM...(Tuesday through Friday) Issued at 212 PM MDT Fri Jul 2 2021 Tuesday...Somewhat similar coverage to Monday with scattered showers and thunderstorms during the afternoon under northwest flow aloft. A bit cooler with the coverage of showers and thunderstorms. Wednesday-Friday...Ridging aloft builds overhead, and with the warmer temperatures aloft, more limited shower and thunderstorm coverage is anticipated, isolated at best. Warmer temperatures also expected with the forecasted 700 mb temperature rise. Perhaps slightly cooler on Friday with a bit more cloud cover. && .AVIATION...(For the 00Z TAFS through 00Z Saturday evening) Issued at 506 PM MDT Fri Jul 2 2021 VFR conditions and SCT cloud cover bases around 8-10k ft continue for all sites across southeastern Wyoming and western Nebraska Panhandle. Isolated thunderstorms will push eastward until 10PM bringing VCTS at sites KLAR and KCYS until 04Z. Gusty winds up to 30kts will arrive in the Nebraska Panhandle starting 15Z for all sites until Saturday evening 00Z. && .FIRE WEATHER... Issued at 212 PM MDT Fri Jul 2 2021 Minimal fire weather concerns as we see daily chances for showers and thunderstorms through at least Tuesday. Afternoon humidity remains above critical levels with good overnight recoveries. Weather forecast to change after Tuesday as high pressure builds back into the area with drier weather and lower humidity. By Thursday and Friday next week...southwest winds forecast to become breezy with afternoon gusts over 30 mph. So looking at possible critical fire weather conditions at that time. && .CYS WATCHES/WARNINGS/ADVISORIES... WY...None. NE...None. && SHORT TERM...GCC LONG TERM...RUBIN AVIATION...AW FIRE WEATHER...GCC
