Area Forecast Discussion...UPDATED National Weather Service Cheyenne WY 542 PM MDT Sun Jun 30 2019 .SHORT TERM...(This evening through Tuesday) Issued at 240 PM MDT Sun Jun 30 2019 So far its quiet across the CWA as convection has to this point remained to the north, and over the mtns of Colorado. Latest HRRR still showing convection developing/moving in over the se Wy mtns by late afternoon and becoming most widespread across EC Wy into the northern Panhandle early this evening. Some heavy rain potential still exists with any storms as they will not be moving fast so will have to keep an eye on that. Activity clears out later tonight. Milder day across the plains Monday as a sfc front remains banked up against the mtns with another round of convection initiating over the mtns in the afternoon. Not as much instability though and shear will be less so severe potential looks fairly low. Similar setup again for Tuesday with lee troughing over the high plains helping to focus convection. .LONG TERM...(Tuesday night through Sunday) Issued at 240 PM MDT Sun Jun 30 2019 Overall pattern changes little through next weekend with weak disturbances moving by and allowing for daily chances for showers and storms. Temperatures look to be a bit below seasonal averages through the period with a cooler air mass settling southward out of central Canada into the northern part of the country. && .AVIATION...(For the 00Z TAFS through 00Z Monday evening) Issued at 542 PM MDT Sun Jun 30 2019 For the 00Z aviation package, some of the model guidance is still bringing down ceilings to IFR ranges for Chadron and Alliance after 09Z. Surface dewpoints still running high that area and forecast soundings show indications of a low stratus deck towards morning, so we went with persistence that area and brought ceilings down again at Chadron toward morning, and think tonight there is a bit higher probability for Alliance, Scottsbluff and potentially Sidney. Otherwise, we don't expect a great coverage of thunderstorms this evening given instability trends but have kept vcnty and periods of showers and thunderstorms going for Cheyenne and Laramie, as well as Sidney unti 05Z. && .FIRE WEATHER... Issued at 240 PM MDT Sun Jun 30 2019 Fire weather concerns are expected to remain low this week with mild to warm temperatures and daily chances for showers and thunderstorms, with conditions remaining non-critical. && .HYDROLOGY... Issued at 202 AM MDT Sun Jun 30 2019 Still monitoring the North Platte River at Saratoga, but the river has finally fallen below action stage. Additional rainfall and snowmelt over the next several days could bring levels back to action stage, but the heaviest rain looks to stay to the east of the mountain ranges. && .CYS WATCHES/WARNINGS/ADVISORIES...
