Active Pattern Shaping Up
Josh Larson @ 8:13 AM
*Wind Advisory in Effect Through 10am Friday*
The weather over the coming week will be changeable and rather unsettled, with high temperatures bouncing from the upper 30s to the low 50s, in addition to chances for both liquid as well as frozen precipitation. Look out, especially, for windy conditions later today into tonight.
Mostly cloudy + windy. Expect more clouds than sun today with a slight chance of a passing shower or thundershower. Highs will be near 50, with winds picking up as the day wears on (from 10-30mph). Tonight will feature strong northwestly winds (20-40mph+) with overnight lows near 30.
Much colder & blustery. Behind today's cold front we'll see partly sunny skies and blustery conditions on Friday with much cooler highs struggling to get out of the low 40s; NW winds 15-25mph will make it feel 10 degrees colder. Clear and cold Friday night with lows ranging from 20-25.
Saturday: Sunny but cool. Expect mostly sunny skies on Saturday with light winds and highs in the mid 40s in most spots; overnight lows will dip down to the upper 20s Saturday night
Sunday: Icy mess?? An area of low pressure will bring precipitation to our region from the early morning hours on. It is possible, due to a layer of cold air close to surface, that we may see several hours (or more) of sleet 0R freezing rain (especially N&W of town) before precipitation changes to plain rain in the afternoon hours. Expect highs only in the upper 30s. Scattered showers continue Sunday night, with lows nearly steady in the mid to upper 30s.
Pattern Overview
A pretty active (and at times amplified) jet stream pattern will allow for multiple waves of low pressure to push across the nation over the next week to ten days; meanwhile, a new shot of cold air building in later today will bring temperatures back to below normal levels for tomorrow through the first half of next week. Despite significant warming aloft, cold air near the surface may be difficult to dislodge (as we saw with our sleet storm earlier in the month), so frozen precipitation on Sunday is certainly a possibility. The next area of low pressure enters the scene late Tuesday though rain is the favored precipitation type at this point. Temperatures may bounce back up above 50 again by Thursday of next week.

Next week's forecast
Forecast highs/lows: 47/32 (normal = 51/33)
Forecast precip: Near normal.
We'll look for skies becoming partly sunny on Monday with high temperatures in the low to mid 40s and lows near 30. Increasing clouds are likely on Tuesday, with showers of rain or wet snow possible late in the day into overnight period; expect highs in the low to mid 40s with overnight lows in the low to mid 30s. Wednesday will feature a return to partly sunny skies, with highs in the upper 40s and lows around 32. Thursday and Friday look to feature partly sunny and generally dry weather with highs quite close to the climatological average of 50/33.
