Area Forecast Discussion National Weather Service Cheyenne WY 341 PM MDT Mon Jul 8 2019 .UPDATE... Issued at 334 PM MDT Mon Jul 8 2019 A Severe Thunderstorm Watch is now in effect for counties in the southern Nebraska Panhandle including Scotts Bluff, Banner, Morrill, Kimball, and Cheyenne Counties until 10 PM tonight. A line of thunderstorms is moving out of eastern Wyoming and into western Nebraska. The main threats with this line of storms are wind gusts up to 70 MPH and hail up to 2 inches in diameter. Heavy rainfall is also possible. && .SHORT TERM...(This evening through Tuesday) Issued at 220 PM MDT Mon Jul 8 2019 Forecast concerns in the short term deal with severe thunderstorm chances/locations both today and Tuesday. Currently...Cold front lays across east central Wyoming this afternoon from a surface low over northwestern South Dakota. Mid 60 dewpoints in the Panhandle with 64 being reported at Alliance...63 at Sidney and 65 at Chadron. Water vapor imagery showing an upper level disturbance moving into the central Colorado/Wyoming state line at this time. 250mb jet around 50-55kts moving into the area with this shortwave. Thunderstorms are beginning to develop along the Laramie Range...moving very slowly to the east. Seeing outflow boundaries emanating from these storms along the I-80 corridor. With the slow storm motions...do expect erratic storm motions. Latest SPC Mesoanalysis showing best instability over the Panhandle this afternoon. By mid afternoon...looking at surface based CAPE values on the order of 4000 J/KG out near Bridgeport. Not a whole lot of shear out there with light low level winds. Effective Bulk Shear around 20kts down near the southern Panhandle. So not really looking at extremely large hail. Better severe hazards may be heavy rain today. Latest HRRR shows on its simulated radar forecast for storms to slowly shift east into the Panhandle through 01Z. Given storms we have received the past several days...did not want to go with no severe storms this afternoon. Do expect severe storms to be on the low end though this afternoon. For Tuesday...Showing a surface boundary pushing southeast out of north central Wyoming Tuesday afternoon with upper level trough moving through late afternoon. Will need to watch the timing on this front/shortwave as SPC does have a Slight Risk area for the northern Panhandle. .LONG TERM...(Tuesday night through Monday) Issued at 220 PM MDT Mon Jul 8 2019 Drier and warmer period for Wednesday through Friday as upper level ridge builds into the area from the south. Could see some fire weather issues as afternoon humidity falls below 15 percent each day...expanding east each day. Fortunately...fuels are still reported as green...so chances for fire starts are small. One final thing for the weekend...backdoor cold front set to move back into the area Friday afternoon/evening from the north. So looks like storms returning for the weekend. For way out there...GFS and ECMWF beginning to show the onset of the monsoon with a Four Corners high setting up and qpf developing over northern Mexico. This qpf makes it up into northern Colorado by mid week next week. Just on time for Frontier Days. && .AVIATION...(For the 18Z TAFS through 18Z Tuesday afternoon) Issued at 1137 AM MDT Mon Jul 8 2019 Latest satellite loop was showing convection already developing across the mountain ranges. This convection is expected to increase in coverage during the remainder of the afternoon. The storms will mostly move east-northeast at 15 to 20 mph and should reach the Nebraska Panhandle by this evening. Gusty west-northwest winds may develop late tonight into tomorrow morning behind the departing shortwave. && .FIRE WEATHER... Issued at 220 PM MDT Mon Jul 8 2019 Scattered to numerous showers and thunderstorms this afternoon...mainly along and south of the Interstate 80 Corridor. One more day of wetting rains mainly east of the Laramie Range for Tuesday. High pressure then builds into the area for Wednesday with very dry air. Afternoon humidity becoming critical each day through Friday...especially along and west of the Laramie Range. Overnight humidity recoveries poor Thursday and Friday mornings. Gusty west winds to 30 mph possible...could lead to areas of critical fire weather. Fortunately...fuels are still being reported as not ready...so fire weather concerns should be minimal. Unsettled weather returns to southeast Wyoming and Nebraska Panhandle by the weekend with increasing chances for wetting rains. && .CYS WATCHES/WARNINGS/ADVISORIES... WY...None.
