The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Cheyenne, WY wrote its last area forecast discussion before the first event at Jul 3, 1:56 PM MST, 2 hours 34 minutes earlier.
Area Forecast Discussion National Weather Service Cheyenne WY 256 PM MDT SUN JUL 3 2016 .SHORT TERM...(This evening through Tuesday Night) Issued at 256 PM MDT Sun Jul 3 2016 Current sfc analysis shows the sfc trough located along the WY-NE border with drier northwesterly flow to the west and moist southerly winds to the east. With good mixing across southeast WY, have seen northwesterly winds consistently gust to 25-35 mph. Still expecting coverage of storms to be rather isolated through the evening with increasing heights aloft and limited instability. Cannot completely rule out an isolated stronger tstm over the northern Panhandle. Warm temperatures will continue into Tuesday with highs near to slightly above normal. Not much change in the synoptic pattern for Monday with mostly westerly and dry boundary layer flow across the CWA. SPC still has the northeastern zones in a marginal risk with good bulk shear and a weak shortwave moving through northern WY. Still think the main threat will be gusty winds from downdrafts with deep boundary layers. A weak front is expected to back into the plains by Tuesday morning. Isolated to scattered storms will develop once again by the aftn. Elevated to near critical fire weather conditions could occur over mainly Carbon county. The models have trended toward weaker winds and slightly higher RH values over FWZ 301 for Tuesday. .LONG TERM...(Wednesday through Sunday) Issued at 256 PM MDT Sun Jul 3 2016 A potent shortwave trough riding the US/Canadian border through the middle part of the week looks to advect an increasingly dry boundary layer airmass across Wyoming on Wednesday. Breezy westerly winds will prevail for much of the forecast area, with fire weather concerns certainly elevated. A cool front dropping south across the plains Wednesday night will offer some relief to hot temperatures on Thursday and low level moisture will increase somewhat. However, conditions across the high country will remain dry and breezy. Precipitation chances still look fairly low, however cannot rule out isolated convection ahead of the front on Wednesday, with a slightly better chance for Thursday within strengthening upslope and better moisture. Shortwave ridging will move overhead for Friday with warming temperatures and mostly dry conditions. Models show better agreement with the upper ridge amplifying over the central and high plains on Saturday in advance of a strong upper low dropping south from the Gulf of Alaska and into the PacNW. Llvl winds will become more of a southerly fetch, promoting better sfc convergence along the Laramie Range. Best mid and upper level moisture will remain well to the north, but some moisture advection within southwest flow along with higher sfc convergence should promote a slightly better chance for showers and storms Saturday afternoon, although coverage will remain isolated. Timing of the Pacific front remains quite different between models for Sunday, so a fair amount of uncertainty remains for thunderstorm chances Sunday afternoon. && .AVIATION...(For the 18Z TAFS through 18Z Monday afternoon) Issued at 1206 PM MDT Sun Jul 3 2016 Fog/stratus has dissipated across the forecast area with mid and upper level clouds streaming overhead. Winds have become quite breezy mainly along and west of I-25 in the wake of a leeside sfc trough that's steadily shifting east across the forecast area today. Think that showers/storms will initiate along the trough axis late this afternoon and could impact KCDR and KAIA. So added vcts to these locations for after 22Z. In addition, models are leaning towards more mountain convection developing in association with an upper level disturbance, and convection could track east into the immediate eastern plains. Otherwise, VFR conditions will prevail tonight along with west-northwest winds. && .FIRE WEATHER... Issued at 256 PM MDT Sun Jul 3 2016 Warmer temperatures will cause minimum afternoon humidity values to fall to 15-20 percent today and Monday. Fire weather concerns will increase a bit for Tuesday and Wednesday, mainly for areas along and west of the Laramie Range, with min RH values around 15 percent and wind gusts to 25-30 mph during the afternoons. Isolated showers and thunderstorms will be possible each afternoon and evening through the middle of next week, however chances of widespread wetting rains will be low. && .CYS Watches/Warnings/Advisories...
