No Temperature Extremes for A WhileJuly 22nd, 2013 at 9:52 pm by Don Paul under 4 Warn Weather
After the drip, drip, drip of perspiration last week (which became a legitimate public health threat for elderly, asthmatics, and infants in non-airconditioned housing), the minor league mugginess at the start of this week will be very easy to take. Even that mugginess will not stick around long. Another fairly strong cold front will cross the region Tuesday night, followed by much cooler and less humid conditions on Wednesday, and only modest warming by the weekend. Another cold front will likely cross our region by Sunday, with cooler than average temps returning as early as Sunday into early next week.
In the overall scheme of patterns, all the major ensemble means (500mb) show no rebuilding of a strong ridge near the Great Lakes or the NE. This will allow occasional brief warmups, but only to “seasonable” warmth, a little above average. These will be followed by cooler periods, but not so cool (or wet) as to cause many disruptions in outdoor activities. We’ll probably see some scattered showers & tshowers or tstorms on Saturday in advance of that next cold front, in addition to those which occur on Tuesday (this week) in advance of the closer cold front.
None of this is to suggest “we’ve peaked”, since there have been hot spells (some of our hottest) in late summer quite a number of times. The recent extraordinary, brutal 600 DM ridge built itself up, after all, following a period of troughiness/coolness in the Great Lakes, NE & Ohio Valley. It IS to suggest, though, that my confidence is high we’ll see no “heat waves” in the next 16 days (date of this post is July 22).
