A Great Way to Start the Week

MON 6/2: Overall, it wasn't a bad weekend. Saturday averaged out mostly cloudy and windy with a few scattered downpours. Sunday, while it began somewhat gloomy, turned out beautiful - the 78F at Hyannis was the mildest we've snice early last October and it was actually a touch humid for a time. The combination of mild temperatures and the humid air mass actually helped trigger a few pop-up showers. One crossed over P-Town during midday, while another moved over the Mid-Cape later in the afternoon. It was truly summer-like, which worked out well given June 1st is the meteorological start of summer (not the official summer solstice which is still 3 weeks away.)

Anyhow, Monday is upon us and while the weekend is gone the nice weather is still here. Both Monday and Tuesday are looking great around the Cape. Plenty of sunshine is expected both days, with just some passing fair weather clouds during the afternoon(s). While this particular air mass is not *overly* warm, it's the wind direction that is making the big difference for us. Winds will blow from the west, which is a downsloping, offshore breeze, favorable for mild temperatures on Cape Cod. Highs both Monday and Tuesday will push into the 70s region-wide, with upper 70s likely again on parts of the Mid and Upper Cape. In fact, computer guidance (MOS) cranks a toasty 80F tomorrow at Falmouth with upper 70s at Hyannis. I'm looking for 79 at Falmouth, 77 at Hyannis and 75 at Chatham. Just about perfect weather.

By Wednesday, another cold front will move eastward through New England giving us a day similar to Saturday. That is, gusty southwest winds will take hold and more clouds than sunshine can be expected. The combination of clouds and southwest winds will likely cap highs in the 60s across most of the Cape. In addition, a few late day showers are possible as the surface front nears the region. However, as things stand right now, most of the organized activity will pass to our north meaning no widespread rain is expected. Depending upon the exact timing of the front and any sunshine we get out ahead of it, a thunderstorm is also a possibility - but again, most of this should remain to our north and west.

Behind Wednesday's system a cool northeast wind will develop and last through the day on Thursday. The onshore flow will lead to a much cooler day, with highs holding in the low to mid 60s. A gusty northeast wind is likely as well and there are signs that a low cloud deck may try and hold on through a portion of the day as the marine layer works westward and gets trapped near the surface. Bottom line, it looks like Thursday is the worst day of the week, with below normal temperatures expected and limited sunshine.

Friday will be a transition day, as the cool air begins to retreat and we get ready to break out into a two day spell of summer weather for next weekend.
