April 25, 2020 – Dry weather with above normal temperatures continue through the middle of next week, with Valley highs in the mid to upper 80s through early next week. Near record highs are expected Tuesday, with Valley locations in the 90s.

Discussion

The upper level ridge will be pushing east today as a trough pushes into the PacNW. Despite the ridge moving east we are still going to see warm temperatures across the region. 850 mb temps will be a few degrees cooler and afternoon highs will generally be 3-5 degrees cooler than what we saw on Friday but still 10-15 degrees above average. The trough to the north will bring high level clouds to the area throughout the day and should also help to hold temps down just a bit. A weak short wave pushes through early Sunday and we will see zonal flow Sunday and Monday. This will bring cooler temperatures with valley highs in the mid 80s. Skis will be mostly sunny on Sunday but a trough passing to the north will bring some cloud cover on Monday.

Upper level ridging builds back in on Tuesday and will bring the return of hot temperatures. 850 mb temp standard anomalies will push to +2 on Tuesday. This is a good indication of very warm 850 mb temps for this time of year and should result in near record highs. Valley highs are expected to make it into the low to mid 90s.

Extended Discussion (Wednesday through Saturday)

Strong ridging continues warm and dry weather through the middle of next week with highs still well above average (10-15 degrees) into Thursday. Cooling trend expected by the end of the week as a series of short-wave troughs displace the ridge to the east and eventually lead to a chance of showers by next weekend.
