BOZEMAN - A slow moving upper-level Low is sitting over western Wyoming Wednesday afternoon and will continue to slowly lift to the NE tonight into Thursday.
Moderate to heavy rain is likely for most of eastern Montana with a flood watch still up for NE counties into Thursday.
Scattered valley rain and higher mountain snow will persist for SW Montana through Wednesday evening. Areas east of the divide will have a higher probability for light steady rainfall and west of the divide look for isolated to scattered showers through midnight.
As skies clear overnight temperatures will drop down into the 30s for most areas Thursday morning. Those of you that picked up rain today will have the best chance for valley fog by Thursday morning. Allow for extra travel time with reduced visibility Thursday morning.
A weak High-pressure ridge will begin to build over the region Thursday and this will kick off a warming and drying trend through the end of the week and into the upcoming weekend. Temperatures should climb into the 70s for most of SW Montana by Friday afternoon but clear skies at night will continue to keep morning lows down into the 30s and lower 40s.
