339 FXUS63 KGLD 071759 AFDGLD Area Forecast Discussion National Weather Service Goodland KS 1159 AM MDT Tue May 7 2024 .KEY MESSAGES... - A Red Flag Warning is in effect for late Tuesday morning through Tuesday afternoon for Cheyenne County in Colorado, and Wallace, Wichita, Greeley and Logan counties in Kansas. Relative humidity values in the teens and winds gusting above 25 MPH are expected. - The next chance for thunderstorms will be Thursday afternoon for the northern two thirds of the area. && .UPDATE... Issued at 921 AM MDT Tue May 7 2024 Gusty winds and low relative humidity values have already been observed this morning across portions of the I-70 corridor. Critical fire weather concerns are expected for much of the area today as gusty winds will help fires spread rapidly. && .SHORT TERM /THROUGH WEDNESDAY NIGHT/... Issued at 516 AM MDT Tue May 7 2024 The upper low is expected to sit over Southeast Montana and Western South Dakota today. A tight pressure gradient sitting over the Tri- State area will lead to another day of breezy westerly to northwest winds with gusts up to 50 mph. The winds are expected to increase shortly after sunrise with the strongest winds lingering from the late morning through the early evening. Temperatures are also expected to warm up with highs in the upper 60s to upper 80s. RH values are forecast to drop into the teens across the entire area beginning around mid-day through sunset. A Red Flag Warning is in effect from 11 AM to 7 PM MDT for Cheyenne County, Colorado as well as Wallace, Logan, Greeley, and Wichita counties. During the evening there is a low chance (~15% and less) for locales along and east of US-283 to see some light rain. Little to no accumulation is expected. Overnight lows are expected to fall into the lower 30s to mid 40s tomorrow night. Little change in the pattern is expected tomorrow as the low continues to stall over the Northern Plains. Dry conditions are anticipated during the day with highs in the 60s to lower 70s. RH values will bring about elevated to near critical fire weather conditions during the afternoon hours as they fall into the mid teens to lower 20s. Winds in the area of lower RH values are expected to gust up to 20 mph while locales north of US-40 gust up to 35 mph. There is another slight chance (~30% and less) for rain during the evening in the northwest corner of the area. Little to no accumulation is expected at this time. Overnight lows are forecast to be in the mid 30s to lower 40s. && .LONG TERM /THURSDAY THROUGH MONDAY/... Issued at 335 AM MDT Tue May 7 2024 For the long term period, Thursday is forecast to be the coolest of the period in the wake of an upper trough axis that swung through the Plains. Highs are forecast to be in the 60`s with a mix of clouds and sunshine. There is also a chance for showers and storms (around 20-60%) as moisture advects into the area and the upper trough axis swings through. Severe weather is not expected with a lack of synoptic forcing and higher surface pressure across the area. For Friday and beyond, the pattern gets a little trickier with the trough axis swinging to the east while a portion of the trough separates and moves west as a small cutoff low. With it, a mix of upper ridging and split flow is forecast to occur which will generally keep temperatures near to above average. Precipitation chances will likely be on the lower side unless the cutoff low can generate a system as it pushes east. && .AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/... Issued at 1154 AM MDT Tue May 7 2024 VFR conditions are expected through the forecast period at both terminals. Northwest winds remain gusty this afternoon around 25-35kts with gusts as high as 45kts. A few passing high clouds are expected through the day. Winds will gradually decrease after sunset, turning to the north. A few mid-level clouds may move in for a period of time this evening. && .GLD WATCHES/WARNINGS/ADVISORIES...
