TEMPERATURES DROP TO LEVELS NOT SEEN SINCE LAST SPRING… A LOW PRESSURE AREA TO OUR NORTH WILL CAUSE SOME CLOUDINESS AT TIMES… THE LOW MOVES AWAY BY MID-WEEK AND THE TEMPERATURES WILL MODERATE… OVERALL, A NICE WEEK LIES AHEAD

To me, the weather Saturday was invigorating. I opened my windows and enjoyed the cool breeze. The low pressure system to our north caused lots of clouds in the area and my neighborhood actually received a shower late the day. Not much rain fell (about a tenth of an inch), but it is amazing how the atmosphere can squeeze out precipitation even when dew points were quite low. All it takes is a very cold pocket of air in the upper-atmosphere to move overhead. This destabilizes the air since cold air is heavier than warm air. Also, cold air cannot hold as much water vapor as warm air so it acts like squeezing a sponge to get those last drops of water out of it. We may see another shower here and there on Sunday, but the chances aren’t that great… less than 20%. Sunday and Monday will be on the cool side and every once in a while, it will be a little on the breezy side. The low over the Northeast is expected to move away and should be gone by mid-week. Temperatures will slowly come up to more seasonal levels. No widespread significant precipitation is expected this week and the dry weather may extend through next weekend… Hurricane Ophelia became a category 4 storm on Saturday, which is quite amazing considering that it attained this strength far to the north away from the warmest waters of the tropical Atlantic Ocean. It was at 32 degrees latitude which is well outside of the deep tropics. Bermuda lucked out since the storm passed far enough to the east to spare them the hurricane conditions that could have swept over the island had the storm been 100 miles to the west. Southeastern Newfoundland may get quite a storm depending on how strong Ophelia is when she gets to that part of the world. Tropical Storm Philippe is expected to keep moving west (and maybe even west-southwest) before it makes the turn to the north later in the period. That’s it for now. Have a great day.
