Warm Front Approoaching
The skies are clouding up right now as a warm front approaches. Take a look at the infrared satellite picture (attached). The band of clouds stretching from the NW nearly due west is associated with the front. Then the clouds take a sharp bend (near the low center) and then heads SW to just north of Hawaii (the latter band is the cold front). In a low-level temperature analysis (with sea level pressure and surface winds), you can see many of these features (see attached), as well as the cooler air still in place over us right now (blue colors).
The clouds will thicken today and showers will reach us very late this afternoon and this evening ( you were going to watch the superbowl anyway, right?). Tomorrow will be the transition day, becoming dry and warmer during the afternoon. Tuesday should be sunny and warm (in the 50s).
Winter really ends here the third week of February, with the risks of major storms of any type dropping rapidly after that. The first third of the remaining winter looks pretty benign.
