Some of these will produce brief... but very heavy rainfall
and may result in urban and/or small stream flooding as well
as potential issues over recent wildfire burn areas.

inches... locally up to 2.00 inches. For central idaho: 0.30
to 1.00 inches.
A Flood Watch means there is a potential for flooding based on
You should monitor later forecasts and be alert for possible
flood warnings. Those living in areas prone to flooding should be
prepared to take action should flooding develop.

Area forecast discussion National Weather Service Missoula Montana 304 PM MDT Fri Aug 22 2014 ..accumulating mountain snow above 6500ft along Continental Divide... ..Potential for patchy morning frost Tuesday and Wednesday next week... Discussion...an area of widespread showers and thunderstorms are starting to fire across the southern Bitterroot and Clearwater Mountains this hour. This activity is forming near a developing mid-level circulation and will very slowly move to the northeast before gradually curving to the northwest. Severe weather is unlikely today, given the cool atmosphere and low cloud tops, so heavy rainfall will be the key threat. This will especially be the case near wildfire burn areas and remain closely watched through the evening. For further details regarding the flooding potential over the next 24 hours and the currently issued Flood Watch, please see the below hydrology discussion. An intensification of precipitation is expected tonight as the mid level circulation further develops and strengthens. The focus for this precipitation will be two fold. The developing late tonight across the southern Bitterroot/Sapphire mtns eastward through the Anaconda- pinter wilderness towards Butte. Locations such as Hamilton, philibsburg, Georgetown Lake, Sula, Lost Trail Pass, Butte and perhaps even as far north as Stevensville will experience a period of heavy rainfall. The next area of focused precipitation will fall along the Continental Divide from the Canadian border southward to around MacDonald Pass. This precipitation will be fed by an extremely moist atmosphere across the upper plains states and further accentuated by strong easterly winds producing up slope flow along the leeward side of The Divide. But descending cold air from Canada will add an additional element of complexity to the forecast and result in the snow level lowering to around 6500ft under this area of heavy precipitation. Thus a Winter Weather Advisory will go into effect for Glacier National Park and the bob Marshall wilderness from 10pm tonight through midday Saturday. Generally speaking, 1 to 3 inches are expected between 6500 and 7000ft with 2 to 5 inches possible above 7000ft. The highest peaks could potentially see upwards of 8 inches under extremely heavy precipitation cores by Saturday morning. Those with plans to adventure in Glacier National Park or other trails along The Divide should plan for cold, wet conditions at all elevations with snow expected across the higher terrain above 6500ft. Conditions will begin to improve throughout Saturday from west to east with most precipitation completed by Sunday morning, revealing a cool, but pleasant Sunday. Next week will start out with another trough over the northern rockies which should increase the shower chances again and keep temps slightly below normal. High pressure then appears to build midweek with cold mornings and warm dry afternoons. This lull in the active fall pattern is transient as computer models continue to show even colder systems coming down from the Bering Sea into the Pacific northwest for Labor Day weekend into the first week of September. /Ss && Hydrology...a Flood Watch remains in effect through midday tomorrow given the potential for convective redevelopment overnight across Clearwater, Ravalli, Missoula, Lemhi, Granite, Deer Lodge and Silver Bow County. Some minor urban flooding (ponding of water on roads) will be possible with some burn areas being threatened. Meanwhile farther north convective precipitation is expected to gradually transition to more light, stratiform rainfall by late this evening. This combined with a slowly falling snow level overnight will inhibit the potential for flooding and thus the Flood Watch for Flathead, Lake and Powell County will be in effect till 10pm. There may be some minor issues with stream decending from The Divide should the maximum rate of precipitation become incredibly intense. However these concerns should remain limited to the east side of The Divide. Aviation...thunderstorms are starting to develop along the terrain of southwest Montana and north central Idaho. Thunderstorm coverage will continue to increase through the afternoon and is expected to transition into steady precipitation tonight. Aviation terminals kbtm, kmso and ksmn will have the best chance to see a thunderstorm this afternoon with the main impacts being brief heavy rain, small hail and gusty winds. Ceilings will also significantly lower and visibility may go below 3 miles under intense rainfall. Kgpi will see some passing showers this afternoon but is expected to see drier conditions as breezy northeasterly winds move in this evening. For tonight, expect steady moderate precipitation at kbtm, ksmn and kmso. Ceilings and visibility will steadily drop through Saturday morning which may cause travel delays. && Mso watches/warnings/advisories... Montana...Lake Wind Advisory until 9 PM MDT this evening for Flathead Lake in the Flathead/mission valleys. Winter Weather Advisory from 10 PM this evening to noon MDT Saturday above 6500 feet for the Potomac/Seeley Lake region...West Glacier region. Idaho...none. && $$ Follow US on facebook and twitter!
