Well the US pattern is pretty quiet these days, albeit hot Out West, much more comfortable once you get east of the Plains where it’s been another day in the 100s.

The tropics have been very quiet of late and here’s a large part of the reason why!

Latest infrared imagery over the tropical Atlantic. There are waves crossing the Atlantic on the southern edge of the dust cloud but there’s nothing of immediate interest at this time.

While it’s in fact been warmer than normal along the East Coast (due to warmer than normal waters offshore), there’s been considerably less 90 degree days than usual for this point in summer.

There have been some bursts of ‘moderate summer heat’ but highs have been subpar the typical blowtorch you typically expect during the heart of the warm season. Rather than mid to upper 90s and 1-3 heatwaves from DC to Boston, there have been NO heatwave this summer to date from Philadelphia northward (3+ days above 90).

Here’s a graphic showing how many 90s there have been in a selection of Midwest and Eastern cities to date verses the summer avg.

Interesting write-up on the lack of 90s in Chicago and Rockford, Ill this summer.

PUBLIC INFORMATION STATEMENT
NATIONAL WEATHER SERVICE CHICAGO IL
206 PM CDT WED JUL 23 2014 /306 PM EDT WED JUL 23 2014/

TUESDAY WAS ONLY THE 3RD OFFICIAL 90 DEGREE DAY OF THE YEAR AT
CHICAGO-O`HARE AND 2ND IN ROCKFORD. IT WAS THE FIRST 90 DEGREE DAY
OF JULY FOR BOTH LOCATIONS. THE LONG TERM AVERAGE FOR 90 DEGREE
DAYS IN JULY IS 8 IN ROCKFORD AND 6 IN CHICAGO. THERE ARE NO 90
DEGREE HIGH TEMPERATURES FORECAST IN THE NEXT SEVERAL DAYS.
ADDITIONALLY…THE 6 TO 10 DAY OUTLOOK FROM THE CLIMATE
PREDICTION CENTER IS INDICATING HIGH PROBABILITIES FOR BELOW
NORMAL TEMPERATURES. THEREFORE…IT IS DISTINCTLY POSSIBLE IF NOT
LIKELY THAT THERE WILL BE NO MORE 90 DEGREE DAYS THIS JULY FOR THE
AREA.

HERE ARE SOME EYE-OPENING STATS IN THE 90 DEGREE DEPARTMENT
SHOWING JUST HOW DIFFERENT THIS JULY HAS BEEN FROM THE SEARINGLY
HOT CONDITIONS IN JULY 2012. INCLUDING JULY 23RD…THERE HAD
ALREADY BEEN 18 90+ DEGREE DAYS IN ROCKFORD AND 16 IN CHICAGO. THE
MONTH FINISHED WITH 21 90+ DEGREE DAYS IN ROCKFORD AND 18 IN
CHICAGO. OF THESE…THERE WERE 5 DAYS OF 100 DEGREES OR HIGHER IN
ROCKFORD AND 3 100+ DAYS IN CHICAGO. OVERALL…MAY THROUGH
SEPTEMBER 2012 HAD AN INCREDIBLE 49 90+ DAYS IN ROCKFORD AND 46 IN
CHICAGO.

THE 1-MONTH OUTLOOK FOR AUGUST AND THE 3-MONTH OUTLOOK INCLUDING
AUGUST…SEPTEMBER AND OCTOBER BOTH FAVOR COOLER THAN NORMAL
CONDITIONS. THUS GIVEN THE LACK OF 90 DEGREE HEAT SO FAR THIS
YEAR…CHANCES ARE INCREASING FOR THIS YEAR TO JOIN
2000…2004…2008 AND 2009 AS THE ONLY YEARS SINCE 2000 WITH
SINGLE DIGIT NUMBERS OF 90 DEGREE DAYS IN BOTH CHICAGO AND
ROCKFORD.

Even down in Dallas, highs have been subpar this summer where they average 18 100 degree days. Recent hot, dry summers have seen 10-15 straight days of 100+ but they’ve only seen 3 such days this year. In fact last week produced 3 days in the 70s, something not witnessed there since I believe 1967. They may stay in the 70s for a few days again next week.

This July so far!

Here’s what’s coming in the 6-10 day!!!

8-14 day

Note the core of chill centred in areas that should be hottest!

Here comes the next big trough which appears to span much of the Southern Tier late next week! Expect more widespread highs in the 70s, even 60s!
