Area forecast discussion, Jul 12, 11:17 PM CDT, 50 minutes before
Area Forecast Discussion...UPDATED National Weather Service North Platte NE 1117 PM CDT TUE JUL 12 2016 .UPDATE... Issued at 1115 PM CDT Tue Jul 12 2016 Updated forecast to add isolated TRW further north in western Nebraska to reflect current WSR88d returns. && .SHORT TERM...(This evening through Wednesday) Issued at 328 PM CDT Tue Jul 12 2016 Quiet and dry conditions continue the rest of the afternoon as surface high pressure remains situated over Nebraska. This high will slowly shift eastward this evening as a weak wave moves off the Rocky Mountains and into the high Plains. This disturbance has the potential to ignite some showers and thunderstorms south of I-80 starting after 10pm. This wave will then combine with a larger system out to the east, resulting in another round of showers across the eastern third of the CWA (mainly east of a Brady to Ainsworth line). These showers will likely begin closer to 5 or 6am. Overnight low temperatures will depend a lot on the cloud cover tonight. Areas with more cloud cover (Southeast CWA) will be in the low to mid-60s whereas areas that have less cloud cover (Northwest CWA) will be slightly cooler in the low to mid-50s. The showers will continue in the east on Wednesday morning and slowly slide eastward through the day. Showers will completely move out of our area by early afternoon as drier air filters into the region from the northwest. Dry conditions will return for the remainder of the afternoon and into early evening. High temperatures will eventually make it into the upper 80s with locations south of I- 80 potentially seeing the low 90s. .LONG TERM...(Wednesday night through Tuesday) Issued at 328 PM CDT Tue Jul 12 2016 Wednesday night through Friday...cool air remains in place aloft with H700mb temperatures below 10C. The flow aloft is mostly zonal and the model consensus suggests a weak upper level disturbance would produce scattered showers and thunderstorms Thursday night. The ECM is a bit slower than the NAM and GFS. The latest consensus suggests the Sandhills and areas south would measure 1/3 to 1/2 inch of rainfall. POPs are 30 to 40 percent and deep convection across the Midsouth appears to be limiting moisture transport into Nebraska with around 1 inch of precipitable water for this event. High pressure moves in Friday stabilizing the atmosphere and pressing the moisture west into the high plains up against the Front range and Laramie Range. POPs are 30-40 percent Friday but could go lower if the forecast models stabilize with this set-up. A 4 way blend of model guidance plus bias correction produces highs in the lower to middle 80s and lows mostly in the 50s. Friday night through Tuesday...a heat wave develops across the Central and Northern High plains Sunday through Tuesday with dew points rising into the mid and upper 60s...possibly higher...and temperatures in the 90s. The thermal ridge rotates north through the Srn High Plains into the Central and Northern High Plains. The H700mb high is over the Midsouth. This should keep the dryline near Ogallala with humidity to the east. Saturday is a transition day with a warm front moving into Nebraska triggering showers and thunderstorms...maybe. Higher dew points may develop given the evaporation of recent heat spells which pushed dew points into the 70s in some areas. The forecast for highs in the 90s looks correct given the position of the dryline. Higher readings may develop along and west of the dry line but this is not shown by the bias corrected data. Isolated thunderstorms are possible Sunday and Monday. The H700mb temperatures of 16C or higher Sunday and beyond could very well produce dry weather during the heat wave. && .AVIATION...(For the 00Z TAFS through 00Z Wednesday evening) Issued at 620 PM CDT Tue Jul 12 2016 VFR conditions will continue across western Nebraska through Wednesday afternoon. Gusty south winds this evening will taper around sunset and gradually shift to northwest overnight. The winds will pick up once again Wednesday early afternoon, most notably across northern Nebraska where gusts may approach 20 kts. && .LBF Watches/Warnings/Advisories... None. && UPDATE...Power SHORT TERM...Kulik LONG TERM...CDC AVIATION...Snively
