PM Update: Warmup midweek, unsettled weather ahead
Monday was the first in a set of what will likely be three summery days — with high temperatures in the 80’s and a warm sun. Autumn-like weather has taken its grip on the areas weather over the last week or so with pleasant days and cool nights. But the below normal temperatures will take a hiatus, however brief it may be, during the next few days. A building ridge in the mid levels of the atmosphere will aid in the development of a southwesterly flow, which will yield increasing mid level temperatures and warmer surface temperatures as well.
High temperatures on Tuesday will reach into the upper 80’s, feeling a bit warmer than Monday. Drier winds, as opposed to the onshore flow which has kept things cooler for the past few days, will make the air feel even pleasantly warm. Humidity will begin to increase as well, but won’t become noticeably uncomfortable until Wednesday. This will signal the approach of a frontal boundary later Wednesday, which will eventually bring an end to the warmer and more summery weather.
