273 FXUS63 KGID 131721 AFDGID Area Forecast Discussion National Weather Service Hastings NE 1221 PM CDT Sun Jul 13 2025 .KEY MESSAGES... - For most, the forecast through Monday night remains dry. Once potential exception comes mid-late afternoon/early evening today...with the potential for a few isolated storms developing along an approaching surface frontal boundary. Kept chances at 20 percent, not all models agree with any activity developing. - Next chances for storms return late in the day Tuesday and continue on through the end of the week. Current best chances are focused on Tuesday evening-overnight, especially across portions of south central NE. Can`t rule out some that activity being strong to severe. More uncertainty and lower confidence remains in storm chance details Wednesday and on. - After a pleasant day on Saturday with highs in the 70s-80s, warmer temperatures return today-Tuesday, with highs in the low-mid 90s by Mon-Tue. Cooler temps return mid-week, with Thur forecast in the mid 70s-mid 80s, before temps climb back into the 80s-90s for next weekend. && .DISCUSSION... Issued at 321 AM CDT Sun Jul 13 2025 Currently... Quiet conditions reign across the region early this morning. Upper air and satellite data showing the forecast area under west-northwesterly flow...set up just west of trough axis extending southward from low pressure in the Hudson Bay area down into central TX. Satellite imagery also showing that outside of a few spots of clouds, most areas are seeing mostly clear skies. At the surface, the pattern remains weak as high pressure continues to slide through the region..keeping winds light and variable. With little cloud cover, light winds, and drier airmass we`ve had in a while...temperatures have had little trouble cooling, lows will end up in the upper 50s-near 60. Today through Monday... Overall, no notable changes were made to the forecast through Monday. For today, models remain in good agreement showing that upper level trough axis continuing to gradually shift east with time, with flow across the area turning more northwesterly and ridging tries to build north over the western CONUS. Through the morning hours, winds are expected to turn more southerly as that surface high also slides further east and lower pressure develops over the High Plains. For the far majority of the forecast area, today/tonight remain dry. During the afternoon hours, models continue to show a sfc trough axis/frontal boundary looking to extend from eastern CO northeastward into SErn SD. While there isn`t any notable upper level forcing expected to move through...this frontal boundary will provide a focus for potential thunderstorm development. A warmer airmass building into the region helps drive temperatures this afternoon back well into the 80s-low 90s...with models showing the potential for MLCAPE values near that boundary exceeding 1500 j/kg and MUCAPE closer to 2000-2500 j/kg. The peak heating of the afternoon and lower level convergence along that boundary will aid in the potential for storms...but with the overall lack of upper forcing, not all models even show any activity developing. At least some isolated storms are not out of the question, and kept the low chances (20 percent) going in the forecast this afternoon-early evening...mainly for areas along/NW of a line from Lexington to St. Paul. Some of these storms being on the strong side are not out of the question with gusty winds/small hail...but the better potential for marginally severe storms looks to be focused just to our NNE, where deeper layer shear looks a bit better. As we get into Monday and Monday night...forecast remains dry for the entire forecast area. Models showing that the ridge building over the western CONUS today is a short lived thing...as another storm system digs south through western Canada into the Pac NW region, turning flow across the Central Plains back zonal. Winds are expected to become more solidly southerly during the day, as low pressure deepens over the High Plains...but not looking at a notable increase in speeds, peaking closer to 15 MPH for western portions of the area. Models continue to show warming 850mb building int the region...forecast highs see another bump up, currently forecast to reach the low-mid 90s for most spots. Afternoon thunderstorms are expected to develop over the High Plains, gradually pushing east, but fading during the evening with the loss of daytime heating. Tuesday and on... Periodic thunderstorm chances make a return to the forecast starting on Tuesday and running through the end of the week...but admittedly the further out in time you go, the lower the confidence gets in the details of those chances. Though the forecast does have low end (20-30 percent) chances creeping into NNW portions of the forecast area during the afternoon hours on Tuesday...most models suggest that no mention of precip is needed prior to 00Z...will see how things trend in the coming days. This first upper level shortwave disturbance slides out of the Central/Nrn Rockies...pushing the development of thunderstorms along a surface cold front that will be approaching the WNW portions of the forecast area late in the afternoon. Some uncertainty lingers with just how far south along this boundary things fire, with models showing warmer mid-level temps/capping having worked back into the area. A complex of storms looks to organize near the central NE/SD border late afternoon-early evening...with models then sliding this activity SE through mainly across the NNE half of the forecast area, aided by the sfc frontal boundary as well as convergence along the nose of an increasing southerly LLJ...with storms more isolated the further south you go. Think this activity would have the potential to be strong-severe...will have to see how things trend today/Mon. Models showing the potential for another shortwave to be quick on the heels of this Tuesday system...driving the storm chances continuing into Wed-Wed night. In the forecast, better chances are Tuesday evening-night (40-50 percent)...with more uncertainty/differences in models for Wednesday keeping those chances in the 20-30 percent range. What happens Tue-Tue night could greatly impact things for Wed (sfc boundary location, available instability, etc)...so hard to have a ton of confidence. Potential remains for additional shortwave disturbances to bring storm chances to the area Thursday-Saturday...but because of continued differences in models and lower confidence, those chances remain at most 20-30 percent. As far as temperatures go, highs on Tuesday are again in the 90s, with southern areas potentially near 100. Cooler temperatures work their way in mid-late week thanks to these disturbances/fronts passing through. Current forecast highs `bottom out` on Thursday with highs in the mid 70s north to mid 80s south...before climbing back well into the mid 80s-mid 90s for next weekend. && .AVIATION /18Z TAFS THROUGH 18Z MONDAY/...
