Today’s temperatures weren’t too typical of late April, with highs only reaching the mid-50s most spots. It happens, though. With a flow off the ocean continuing tonight and into tomorrow, albeit eventually relaxing, we’re not looking at a major warm up in the near term.

Through Tonight: With the loss of daytime heating to burn through the cloud deck, we see a bit of a thickening and lowering of the deck overnight. We’ll call it mostly cloudy on the whole, with maybe even some drizzle here and there. Lows make the upper 30s to mid-40s. Winds from the northeast stay up around 10 mph with higher gusts.

Tomorrow (Tuesday): The marine flow begins to relax, but it’s still around, so we probably see no better than partly cloudy skies after we burn off the thicker drizzly stuff early. Highs range from the upper 50s near the bay to perhaps as high as the mid-60s inland. Winds are still mainly from the east, but lighter than today.

Never-ending winter? If you think the chill around here is annoying, at least we aren’t in the Denver area to upper Midwest zone. Yet another winter storm is impacting the region (see pictures of a new foot of snow in Rapid City, SD), and it’s expected to dump up to a foot of snow on Minnesota tonight. Minneapolis/St Paul is under a winter storm warning, and this storm should push their April total past 20 inches.
