Area Forecast Discussion National Weather Service Cheyenne WY 1140 PM MDT Sat Jun 30 2018 .UPDATE... Issued at 503 PM MDT Sat Jun 30 2018 Please see latest 00z Aviation Discussion && .SHORT TERM...(This evening through Monday Night) Issued at 1256 PM MDT Sat Jun 30 2018 Tonight...Progressive shortwave trough aloft works eastward across our counties late this afternoon and early this evening, helping to spawn scattered to numerous showers along with isolated to scattered thunderstorms through the evening. Convective parameters indicate about 1000 to 1500 J/kg of CAPE available with impressive shear values around 50 knots. Could see a few strong to severe thunderstorms mainly over far southeast Wyoming and the southern Nebraska Panhandle where the Storm Prediction Center indicates a slight risk. Subsidence in the wake of the shortwave trough aloft should put a quick end to showers and thunderstorms by late this evening with clearing skies after midnight. Sunday...Dry and warmer with brisk west northwest flow aloft and 700 mb temperatures rising to near 12 Celsius, yielding maximum temperatures from the upper 70s to mid 80s. Sunday night...Not quite as cold as tonight as the airmass moderates. Monday...Decent warming trend continues as the flow aloft backs to west southwest, and as the airmass continues to dry. High temperatures back into the 80s to lower 90s with 700 mb temperatures near 16 Celsius. .LONG TERM...(Tuesday through Saturday) Issued at 1256 PM MDT Sat Jun 30 2018 Tuesday...Some moisture returns with southwest flow aloft and thus expect isolated afternoon and evening showers and thunderstorms primarily along and east of Interstate 25 where the moisture will be most prevalent. July 4th...The holiday looks mostly dry with limited low and mid level moisture and warm temperatures aloft limiting convective potential. Thursday...Will see some increase in low and mid level moisture under weak southwest flow aloft, with isolated showers and thunderstorms late in the day mainly along and east of Interstate 25. Friday...With the ridge mainly overhead and warm temperatures aloft, will see limited chances for afternoon and evening showers and thunderstorms, though cannot rule out isolated thunderstorms mainly over the higher terrain and mountains. Saturday...Another mostly dry day expected with warm temperatures aloft limiting convective potential on the western periphery of the upper ridge axis. Continued quite warm with maximum temperatures in the upper 80s to upper 90s at lower elevations with 700 mb temperatures near 17 Celsius. && .AVIATION...(For the 06Z TAFS through 06Z Sunday evening) Issued at 1140 PM MDT Sat Jun 30 2018 VFR/SKC.
