Great Beach Day Ends The Work Week, Watching Possible Storms Saturday

Another warm day more like mid-summer is on the weather menu. Itís ironic of course that many of you wanted this weather for your vacations in July and August, but the summer brought more dry and pleasantly warm air rather than the hot and humid stuff.

My fellow meteorologist Eric Fisher tweeted yesterday that after tomorrowís day again in the 80s we will have experienced our longest stretch of 80 plus weather of the year. Itís pretty amazing itís occurring in September.

If this same pattern had set up in mid-July most of the high temperature would have been in the 90s, not the 80s. We have lost about 2 hours and 20 minutes of possible sunlight since the summer solstice and therefore gained that much darkness. This means the nights, even in this pattern, are able to cool more and the days wonít get quite as hot as they would have 8 weeks ago.

The highs today will reach the mid to upper 80s and a few spots will no doubt touch 90F for a couple of hours this afternoon. The humidity wonít be oppressive, but it will be rising. Itís not until tonight and tomorrow that the air will have that pure tropical feel to it and when it reaches this level, most of us are ready for it to end.

The good news is that a cold front will be sweeping east moving the summer air out to sea tomorrow. The bad news is this front is likely going to produce widespread showers and thunderstorms and some of these could reach strong to severe levels.

The map below is issued by the Storm Prediction Center in Norman, Oklahoma. They are part of the National Weather Service and severe weather is their main focus.

Tomorrow, New England has a slight risk of severe weather. Notice we have the highest risk of big thunderstorm, but the risk itself is at the lower end of the scale. This means we will have to keep a close watch on developing thunderstorms in the afternoon.

The radar prediction for tomorrow shows a line of storms in the afternoon marching eastward. The most likely time of these storms will be from about 2PM until 9PM from west to east across New England. This doesnít mean storms canít occur a bit earlier or later, that is just the most likely scenario. If you do see showers and storms they will last about 1-2 hours. Since the window of rain is small, I would still go ahead with outdoor plans, just be aware they might be interrupted.

I'll be tweeting updates on the storms tomorrow you can follow me @growingwisdom there.

Once the front clears the coastline, drier air follows. The night will become progressively cooler and more importantly drier tomorrow. It might be after you go to sleep that it feels a lot better, so air conditioning could be in order early in the evening. By Sunday morning you can fling the windows open and shut off the AC for a while.

If you donít see rain from the storms tomorrow, it might be a while before we get wet again. Thereís going to be a storm passing south of the area around Tuesday. The map below, which shows the total amount of rain for the next week, has our area getting some rain from the showers tomorrow, but the big swath of rain to our south off the coast indicates to me the next possible storm misses us.

Finally, while I was putting together the images for this blog entry I noticed the future radar projection for tomorrow has a nice rendition of Hurricane Norbert off the coast of Baja, California. This storm will bring heavy rain and some wind to Baja before it weakens on its northward track.
