Nightly Freezing Temps into Tuesday
Good afternoon folks! Another round of ridgeline snow fell last night above 5500', although totals were under an inch and a dusting in many spots; still wild to see snow anytime during May. Snowshoe Mountain picked up 3"! We'll deal with another March-like afternoon today, followed by a widespread freeze tonight as temps plummet to the upper 20's - low 30's. Sunday pushes temps to roughly 10 degrees warmer than today as more sunshine hangs overhead, cooling down slightly on Monday due to NW flow setting up shop in the wake of a weak frontal passage late Sunday. High clouds stream overhead Tuesday and temps moderate a bit, continuing their rise into Wednesday which is when we expect to return to normal levels for mid May. By the end of next week temps will make a return to the low 80's and so will pop up showers that we typically see during the summer months.
We'll deal with widespread freezing temps tonight (Saturday night) as high pressure slides overhead and ideal radiational cooling occurs, bringing temps down to the upper 20's - low 30's across the valleys, while the ridgelines sit in the low - mid 30's; all under clear skies.
After a frosty start to Mother's Day we'll warm up nicely as sunny skies continue overhead, coupled with a light southerly flow that will push temps to the mid 50's - upper 60's depending upon elevation. A cold front will swing through during the early evening hours and passing clouds will be the main result, followed by NW winds around 10 - 20mph after midnight. Low temps will dip into the low - mid 30's above 4000' but NW winds should negate any frost from forming, however patchy frost is possible in the deeper hollers and coves as temps flirt with the upper 30's across the valleys.
We kick off the work week with a breezy day and sunny skies will continue across the region, although it won't amount to much as temps only make it to the mid 40's - upper 50's depending upon elevation. NW winds will gust to 30mph above 4500' and remain steady around 10 - 15mph across the entire region all day. Winds calm down gradually as we move through the overnight hours, with mostly clear skies overhead and temps settling into the low - mid 30's once again (yes, another chance for frost)!
We'll gradually transition to a southerly flow as we work our way through the middle of the week, with high clouds passing overhead Tuesday and Wednesday. Temps will warm from the mid 60's Tuesday, climb to the low 70's Wednesday and by the time southerly flow truly sets up shop on Thursday, temps will make a run at the 80°F mark!
We'll stop here and circle back on Monday. Make sure your plants are protected tonight, Sunday night and again Monday night! We should be clear off frosty temps by Tuesday night.
