NWS Goodland, KS wrote its last area forecast discussion before the first event at Apr 30, 9:53 PM MST, 2 hours 7 minutes earlier.
Area Forecast Discussion National Weather Service Goodland KS 1053 PM MDT Sat Apr 30 2022 .UPDATE... Issued at 302 PM MDT Sat Apr 30 2022 High Wind Warning has been allowed to expire on time. Wind gusts will remain in the 40 to 50 mph range for another few hours becoming light and variable around or shortly after sunset. && .SHORT TERM...(This evening through Tuesday) Issued at 215 PM MDT Sat Apr 30 2022 Tonight...a 1017mb surface high moves over the area allowing for light winds under some scattered high clouds after midnight. Low temperatures are forecast to be in the lower 30s to around 40. Sunday-Sunday night...a closed 557dam upper level low pressure center is forecast to reach central Utah by the end of the day, moving east toward the Palmer Divide by 12z Monday. At the surface, the pressure gradient between the surface high to our east/northeast and developing low pressure over south central Colorado will produce some breezy to windy southeasterly winds during the late morning through afternoon hours, mainly west of a line from Benkelman to Oakley. Surface based instability begins to increase mostly across far eastern Colorado in the afternoon. A weather disturbance is forecast to move into the area (mostly parts of far eastern Colorado) in the mid to late afternoon supporting a chance for showers and thunderstorms. This area is under a Marginal Risk for severe thunderstorms from the Storm Prediction Center. High temperatures are expected to be in the upper 60s to lower 70s. During the overnight hours most of the elevated instability is on the back edge/behind the northeast moving weather disturbance that moves across the entire forecast area. Its possible for a few storms to be severe otherwise we should see some much needed beneficial rainfall with precipitable water values generally 0.75-1.10 inches. Likely to categorical pops look great with rainfall amounts during the night generally a quarter to half inch. Low temperatures range from the middle 30s in Yuma county to the middle 40s from Hill City to Leoti south. Monday-Monday night...the upper level low pressure center is forecast to move on top of the forecast area by noon then toward Grand Island, NE by the end of the day. Overnight, its expected to move northeast into Iowa. The surface low moves toward southeast CO/southwest KS by noon then into central KS by the end of the day. A tight pressure gradient exists and will produce wind gusts up to 40 mph. Abundant cloud cover is expected in the morning due to the easterly wind with some breaks in the clouds during the afternoon, mainly south of the interstate. As a result, the coolest daytime highs will be along and north of the interstate with lower 40s to lower 50s expected while to the south lower 50s to upper 60s are expected. Low temperatures fall into the middle 20s to around 30 in far eastern Colorado with upper 20s to middle 30s along/east of the CO/KS border. Regarding precipitation chances, the highest chances during the day will be generally along and north of the interstate where better moisture in the 850-500mb exists along with higher precipitable water values up to .8 inches. Not much in the way of instability both surface or aloft so severe threat should be rather low. Precipitation chances decrease rapidly in the evening with dry conditions after midnight. Tuesday...our attention turns to another closed upper level low which is expected to be centered over the Utah/Idaho border through the day. Dry conditions are expected although we cant rule out some drizzle and fog which could deposit a hundredth or so of moisture in the morning due to a saturated boundary layer. High temperatures remain a bit cool compared to normal with middle 50s to middle 60s expected. Southeast winds become breezy along and west of the CO/KS border in the afternoon ahead of the approaching upper low. .LONG TERM...(Tuesday night through Saturday) Issued at 130 PM MDT Sat Apr 30 2022 Another upper low will be approaching the central Rockies Tuesday night with rain chances continuing through the day on Wednesday and possibly Thursday. Still timing differences between the models, with the GFS faster (rain chances beginning Tuesday night and ending Wednesday night) compared to the ECMWF (rain chances beginning Wednesday and ending Thursday night). QPF is all over the place, but there is some potential for an inch or more to occur over a day or two in eastern areas (ECMWF). However, given all of the discrepancies, details of the next rain event are rather sketchy at this point, other than to say there will be a chance for rain Tuesday night through Thursday. Temperatures will be below normal during that time as well. Given limited instability, severe chances should be low. By Friday and Saturday, should start to see shortwave ridging build over the area with dry and warmer conditions. High temperatures should be back into the lower 70s by Saturday. && .AVIATION...(For the 06Z TAFS through 06Z Sunday night) Issued at 1034 PM MDT Sat Apr 30 2022 VFR conditions will prevail at MCK and GLD through the 06Z TAF period with mostly clear skies through the remainder of the night and much of the day on Sunday. Scattered thunderstorms will develop over eastern Colorado and lift northeastward across the central High Plains region after 00Z Sunday evening. Storms are expected to move across the GLD site after 04Z and the MCK site between 05-06Z Sunday evening. Being in closer proximity to the increasing pressure gradient between the surface high over the plains and the deepening low over the 4-corners region that moves into southeast Colorado after 00Z Sunday evening, GLD will have southeast winds that will gust to around 25kts after 16Z and remain gusty out of the southeast through the end of the 06Z TAF period. MCK will see winds turn to the southeast after 12Z, but will not see the gustiness until about 05Z as winds turn more easterly as the low moves out onto the plains. && .GLD WATCHES/WARNINGS/ADVISORIES... KS...NONE. CO...NONE. NE...NONE. && UPDATE...99 SHORT TERM...99 LONG TERM...024 AVIATION...LOCKHART
