Tonight: Cloudy with rain showers mixing with and changing to snow showers. A trace to 1” of snow is possible with up to 2” possible in the higher elevations. Icy spots with areas of dense fog. Low: 29-34
Friday: Any morning snow showers end with a slight chance of a few flurries or a sprinkle through the day. Lots of dry time is expected. High: 35-40
Friday Night: Slight chance of snow showers. Unseasonably cold. Low: 14-20
Rain showers will change over to a mix of rain and snow in the lower elevations with snow likely in the higher elevations. Minor accumulations are possible. Rivers will rise, but river forecasts have significantly decreased crest heights in the last 24 hours. However, isolated ice jam flooding is still a possibility. Continue to monitor the rivers through tonight and Friday and be ready to move to higher ground if water starts rising. Notify authorities if it does. It will turn colder for Friday and Saturday before temperatures climb back into the low 40s by Sunday and early to mid next week.
Detailed forecast discussion:
Colder air is slowly filtering into the area this afternoon. The precipitation should slowly decrease through the evening and into the overnight, but it will also mix with, and change to, snow from northwest to southeast. The higher elevations could possibly see an inch or two of snow by morning. If any snow accumulates at all in the valleys, it will be minimal and likely be on grassy and elevated surfaces only. With temperatures dropping to around and below freezing, there could be some icy spots as standing water freezes. Winds will be light and some dense fog is likely across the area. Vertical atmospheric temperature profiles also suggest a few pockets of freezing drizzle could develop tonight. Lows will range from 29 to 34.
Expect plenty of clouds and possibly a few leftover morning snow showers. Most of Friday looks dry with just a tiny chance of a spot sprinkle or flurry in the afternoon. Highs will range from 35-39. Saturday will be unseasonably cold with highs likely struggling to 30. Both weekend days look dry for now.
Sunday looks like the pick of the weekend with sunshine and more seasonable weather. Highs will be around 40. Monday and Tuesday could bring a few mixed showers with highs both days around 42. Wednesday and Thursday look quiet with highs climbing into the upper 40s and low 50s.
