Area Forecast Discussion National Weather Service Goodland KS 1134 PM MDT Wed Mar 31 2021 .SHORT TERM...(This evening through Thursday) Issued at 248 PM MDT Wed Mar 31 2021 At the beginning of the forecast period today, the CWA is underneath the front part of an upper air ridge that resides over the western CONUS. This setup aloft yields a northwesterly flow over the CWA. At the surface, dry conditions continue through out the CWA with an surface high in northeastern KS. Winds are expected to blow from the north-northwest between 10-15 mph through the evening hours. Tonight, the northwesterly flow is expected to continue through the night over the CWA as the upper air ridge continues to slowly work its way eastward. Models also show a closed low off the coast of Southern CA slowly making its way eastward as well. Precipitation is not expected overnight in the CWA while winds become lighter and variable before shifting to a southerly direction after midnight. Overnight low temperatures should remain in the middle to upper 20s range across the CWA. On Thursday, model guidance shows the ridge making its way over the CWA changing the flow aloft more westerly by the evening hours. Models also show the aforementioned closed low open into a trough and make its way near the UT/AZ border overnight. At the surface, a surface high looks to move into the OK/TX area with the ridge aloft. While dry conditions continue for the CWA, there is the possibility for elevated to near-critical fire weather on Thursday due to lower RH values and stronger wind gusts expected during the afternoon. Daytime high temperatures expect to range from the middle to upper 60s with overnight lows in the lower to upper 30s. .LONG TERM...(Friday trough Wednesday) Issued at 110 PM MDT Wed Mar 31 2021 The long term period will be characterized by warm temperatures and overall dry conditions. A short wave trough aloft moves east of the Rockies and across the Northern Plains on Friday with the low pressure center aloft moving out of the far southwest U.S. moving more slowly across the southern Rockies Friday night and into west Texas by late Saturday. A broad ridge will persist across the mid-section of the U.S. through the remainder of the weekend. The overall pattern begins to shift early next week as a trough starts deepening and moving into the far western U.S. Model agreement on this upcoming trough is poor at this point with a range of solutions identifying the trough anywhere between the central Rockies and the far eastern Pacific by Wednesday afternoon, so have not strayed any from the guidance being produced by the National Blend of Models from this weekend through the middle of next week. The lee trough along the Front Range fragments with a portion of it moving east across the central High Plains Saturday night and early Sunday, with a reestablishment of the lee trough along the Front Range that deepens again Sunday into Monday before moving eastward across the forecast area around early Tuesday morning ahead of a cold front that brings more moderate temperatures to the region by Wednesday. Near Record to Record high temperatures are possible across far eastern Colorado and far west central Kansas on Sunday and Monday along with a potential for Critical Fire Weather conditions across the western portions of the forecast area on Monday and Tuesday next week. Record High Temperatures and Fire Weather conditions are detailed more extensively in subsequent sections of the Forecast Discussion. && .AVIATION...(For the 06Z TAFS through 06Z Thursday night) Issued at 1134 PM MDT Wed Mar 31 2021 VFR conditions will continue at KGLD and KMCK terminals through the TAF period. Light and variable winds at both sites will increase to around 14-17kts with gusts as high as 22kts by 15Z at KGLD and 17Z at KMCK. Southerly to south-southeasterly winds will persist at both sites through the forecast period, decreasing to under 12kts after 00Z. && .FIRE WEATHER... Issued at 110 PM MDT Wed Mar 31 2021 The portion of the forecast area west of a line from Stratton, Nebraska to Leoti, Kansas could see at least Elevated Fire Weather conditions each afternoon from Thursday this week through Wednesday of next week as relative humidity values dip below 20 percent with winds gusting between 15 and 20 mph. Some localized areas could briefly reach Near-Critical Fire Weather conditions as relative humidity values drop to around 15 percent and winds gust as high as 25 mph. Confidence is now highest in coincident areas of wind gusts above 25 mph and relative humidity values less than 15 percent for 3 hours or more occurring on Monday and Tuesday over portions of far eastern Colorado and extreme west central Kansas. && .CLIMATE... Issued at 110 PM MDT Wed Mar 31 2021 With the warmest temperatures of the upcoming week expected on Sunday, April 4th and Monday, April 5th, there is a potential for a few record temperatures to be met or broken mainly in the vicinity of the far Eastern Colorado border. High temperatures on Saturday and Tuesday will be a few degrees cooler than Sunday and Monday, keeping record highs a little further out of reach on those days. Here are the record High Temperatures in degrees Fahrenheit and the years they were set for April 4th and 5th.
