AM All Zones Update: Cut-off Low with Heavy Rain Today, Warmer Late Week

/by

A cut-off low that we have been discussing here since last week, will finally bring some heavy rainfall to much of the region, this afternoon and early evening. Afterward, some unsettled weather will continue over the couple of days, as the cut-off low weakens and slowly moves away from the region. Then more pleasant weather with much warmer than normal temperatures return for the end of the week and start of the weekend. But a backdoor cold front may spoil the warm up later in the weekend! Get more details on the weather over next several days in a breakdown below.

Analysis: Two Disturbances to Watch

/by

Good evening! We had a lovely Spring day with sunny skies and temperatures in the 60s, but winds are picking up a bit along the coast as winds turn more onshore and a marine layer develops. For more on these short term changes including the chance for light rain on Wednesday night into Thursday, please be sure to check the dashboard and read our latest zone article updates! This article will be focused on the two upcoming disturbances: one for Thursday night into Friday, and another one for Sunday into Monday. Both could bring periods of heavy rain, but uncertainty is still high as it’s also still possible that little rain falls from either system.

After the periods of light rain on late Wednesday night into Thursday, a stronger storm system will be traversing the Great Lakes. This will allow a warm front to surge northward towards the area, which may place us in the warm sector. There is still uncertainty with how far north this warm front gets — they often can get a bit hung up this time of year and not progress as far northward as model guidance indicates. This is important because if the warm front stays further south, we may not enter the warm sector and thus may remain too stable for heavy showers and thunderstorms.
