Friday & the weekend: Cool start, warming up, showers late Sunday

/ January 26, 2023 at 10:48 PM

Cool weather will kick off Friday and the weekend as we sit under the influence of high pressure for a couple days before it shuffles back offshore later Saturday into Sunday. Expect lows in the mid-30s on Friday before warming just into the mid-50s despite plenty of sunshine; this is due to a trough axis in the mid-levels passing by to the north. We’ll see this feature give way to more zonal (west-to-east) flow as we get into Saturday, which will start around freezing but will rebound into the low 60s as high pressure begins to move east of the area. Temperatures — and dewpoints — then climb quickly on Sunday ahead of a storm system that’ll kick off rain showers in the afternoon, with the best chances for rain arriving late Sunday into Monday. Highs on Sunday should top out in the mid-to-upper 60s, foretelling a fairly warm end to January with highs next week approaching the 70° mark to close out the first month of 2023.
