What forecasters said that day
The local office's own words before this special weather statement went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Missoula, MT wrote its last area forecast discussion before this special weather statement went out at Aug 2, 2:45 PM MDT, 6 hours 9 minutes earlier.
Area forecast discussion, Aug 2, 2:45 PM MDT, 6 hours 9 minutes before
Area Forecast Discussion National Weather Service Missoula MT 245 PM MDT Sat Aug 2 2014 .DISCUSSION...An upper level wave brought scattered showers and a few embedded light thunderstorms from 5 am MDT this morning through early this afternoon across southern Idaho County northeast to Granite County. The activity produced several dozen lightning strikes mainly over mountainous areas. As this wave moves eastward, scattered thundershower activity will fire up from Ovando south to Butte this afternoon. Behind it, there is still the potential for showers to develop but may remain over the terrain. Another wave that has produced showers and thunderstorms over northeastern WA and the ID Panhandle will help to induce activity over northwest Montana this afternoon and evening with main threats being gusty winds, lightning and locally heavy rain. The next upper level wave that weather models are keying on has been tracking across central Oregon and is forecast to track across central Idaho into western Montana by daybreak Sunday. A few of the high-resolution models have been hinting at a few storms breaking out over eastern OR/WA and moving over the Camas Prairie by late this afternoon into early evening. If they keep their strength, there is the possibility for strong wind gusts with these storms. As the wave moves through the area tonight, there is a chance for night-time thunderstorms especially across Clearwater and northeastern Idaho Counties in Idaho and from Mineral to Ravalli Counties. Main threats would be locally heavy rain, lightning and gusty winds. On Sunday there will be a general chance for diurnal thunderstorms developing with the higher terrain seeing the best chance for activity. Temperatures will remain above normal for this time of year. Monday, a very wet disturbance that can be traced back to the southwestern us monsoon will graze the northern Rockies. Uncertainty remains high with the trajectory of the system as some models recently started trending to a more southeasterly path over Wyoming. And considerable disagreement among the many weather models continues to cloud the forecast. But, confidence is growing that at least Lemhi county, Idaho, and southwestern Montana will be impacted. The air mass with this system is extremely moist for the Northern Rockies, and has tremendous potential for heavy rain. However, such a moist air mass will cause a lot of cloud cover weakening the biggest driver of rain this time of year, thunderstorms powered by strong surface heating under initially clear skies. As a result, rain is expected to be more wide spread and moderate with a few embedded thunderstorms. Portions of Lemhi county and southwestern Montana may receive half an inch to an inch of rain Monday and Tuesday. The main impact of this could be to set back fire season in the affected area. Portions of central western Montana and the rest of central Idaho will receive less rain, but could still get pretty wet. Northwest Montana may get a few showers, but will be relatively dry overall. && .AVIATION...Widely scattered thunderstorms are developing across the region. KGPI and KBTM look to have the best potential for a passing storm through 03/0300z. A weak weather disturbance may kick off a few thunderstorms after midnight potentially impacting all terminals. Slight chances of storms return again Sunday afternoon which may impact all terminals. && .MSO WATCHES/WARNINGS/ADVISORIES... MT...None.
