843 FXUS63 KLBF 310508 AFDLBF Area Forecast Discussion National Weather Service North Platte NE 1208 AM CDT Fri Jul 31 2026 .KEY MESSAGES... - Scattered strong to severe thunderstorms are expected this afternoon into the evening for areas along and east of Highway 83. The main threat will be damaging wind gusts but an isolated hail and tornado threat cannot be ruled out. - Warm, dry conditions expected heading into the weekend and through Monday, which will bring about elevated to near critical fire weather concerns. - A potential return to seasonal highs and some light precipitation chances expected through the middle of next week. && .SHORT TERM /THROUGH SATURDAY/... Issued at 214 PM CDT Thu Jul 30 2026 Strong to severe thunderstorms will be possible across most of the region, but especially across north central into central Nebraska. An upper level shortwave from the Mountain West will continue to move eastward into our region by mid afternoon. This should interact with the unstable environment and help provide better lift for thunderstorms this evening. A surface low has developed in southern South Dakota to further help initiate cells as the cold front moves through. Dewpoints remain high (low to mid 70s) across north central to central Nebraska along with ample MUCAPE at 2500 - 3000 J/kg should provide an environment for severe growth. CAMs have had general agreement in starting out supercellic in nature with modest 0-6 km CAPE at low to mid 30 knots. While H850 temps are on the warmer side in the mid to upper 20s C, the MUCAPE mentioned above along with modest lapse rates shows that an isolated large hail threat is possible. Damaging wind gusts will be the primary threat as storms transition into a potential line later this evening. CAMs have been in fair agreement of cells bunching into a line early this evening and moving southeastward into central Nebraska. This also matches up with a large area of about 1000 J/kg DCAPE. With abnormally high Pwat values of 1.91 inches as well as low and mid RH values being near the 75% threshold from our 18z sounding there is a signal for storms to be potential flood producers regardless of severe potential. As such, a Severe Thunderstorm Watch has been issued for most of the CWA until 9 PM CDT which lines up with CAMs on when most of our convection should move out of our region. Friday will start to bring a return to warmer, drier conditions as a ridge moves in from the west. Highs will be in the mid to upper 80s with gusty northerly winds up to 30 - 35 mph. This will promote some elevated fire concerns even humidity only being around 40 percent. && .LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/... Issued at 214 PM CDT Thu Jul 30 2026 Summer heat will build back over the weekend as an upper level ridge moves in from western CONUS. As it stands, guidance is currently suggesting H850 temps in the 20 - 30C with surface highs cresting the mid 90s on Saturday with surface highs reaching even higher to triple digits in the eastern Panhandle on Sunday. These warmer temperatures along with afternoon humidity values dropping to 20 - 25 percent across the eastern Panhandle into the Sandhills, with moderate probability (30 - 50%) of humidity dropping into the teens, especially Sunday. Combine this with gusty south southeast winds and little to no wetting precipitation expected, will make for the likely return of elevated to near critical fire weather concerns for the western half of our CWA. Will continue to closely monitor the forecast for any increased confidence with this trend. By Monday afternoon, the ridge will begin to breakdown as an upper level trough begins to dig into the region from western Canada. This will largely be the driving force for stronger winds and heightened fire weather concerns. LREF guidance suggests at 50 - 70% probability of wind gusts in excess of 30 mph gusts across the region. With highs in the mid to upper 90s and afternoon humidity will drop to low 20s to upper teens along and west of Highway 83, this will make for near critical fire weather conditions, where if the trend holds, could warrant some fire weather headlines, depending on how receptive fuels are to recent rains. This will be another trend to monitor for any changes. A cool front will push through Monday night, returning to near seasonal high temperatures for the rest of the week. There is some signal for better precipitation chances Monday night with a cool front moving in but, there remains some ensemble disagreement over just how much precipitation will fall during this time with GEFS and ECMWF members showing 0 - 0.1" while GFS being on the aggressive side with up to a half inch of rain by the end of Wednesday. && .AVIATION /06Z TAFS THROUGH 06Z SATURDAY/... Issued at 1204 AM CDT Fri Jul 31 2026 As a cold front moves through an area early this morning, an area of low stratus clouds (MVFR and local IFR conditions) are expected along and northeast of a BBW to VTN line. These ceilings should lift after sunrise. Winds will become gusty from the north to at 15-25 kts during the day Friday. Winds diminish quickly Saturday evening and shift to the northeast. && .LBF WATCHES/WARNINGS/ADVISORIES... None. && $$ SHORT TERM...MRS LONG TERM...MRS AVIATION...Taylor
