Summer Warmth Slow to Take Hold Before True Summer
The Memorial holiday weekend is almost upon us and one thing for sure weather-wise. There is no sign of the blazing heat of summer.
Sure there will be a 2 day flirtation with hot weather as we hit the mid 80s with high humidity early this week. But no sooner do we crank the AC back up will we be opening up the windows again by late week and the holiday weekend.
Turns out there is a quirky thread running through our weather since mid fall; namely, an overall cooler than normal weather pattern remains in control.
This pattern began with a day after Vets Day snowfall and has steamrolled through the harshest winter in nearly 20 years and through most of the spring. Hey just 4 weeks ago, we had our last snow of the season melt away on Income Tax Day (April 15).
Since then the pattern has occasionally lapsed into summer (a handful of days have registered highs in the mid to upper 80s) only to revert to its long term cooler than normal mean.
Take Sunday and Monday mornings when lows dipped into the upper 30s for most with a few patches of late season frost trying to nip some early tomatoes and geraniums.
The overall driving forces responsible for this pattern include the chilly jet stream remaining far enough south into May to give us a periodic dosing of rain followed by chilly winds from the north.
In addition, the damp and cold ground left behind from winter and the abnormally chilly water temperatures of our Great Lakes and other major waterways have added to the cool clime!
So it will likely take a good 2 weeks, into early June before the ground and air can catch up to the calendar to sponsor our first 90 degrees days of the season.
My summer forecast for 21 days of 90 degree heat in Charleston and 17 in Huntington suggests a rather “normal” summer at pools and playgrounds for the kids on summer vacation.
