HUMIDITY JUMPS

What a surge in humidity! Long gone are the 40° temperatures from early Friday morning!  The dew point, the measure of moisture in the air, has surged bringing back a more typical summer feel.  Late Saturday the dew point change from 24 hours previous was a stunning 20° – a huge jump.

No all day rains are coming. There will be plenty of dry time Sunday and for many of the days in the upcoming week.

CHECKING IN ON AUGUST 2014

Mid way point of August and the cool trend continues.  August 2014 now ranks 11th coolest all-time with an average temperature of only 71.1° – coolest August in 10 years.  Rainfall has slowed since the month began with only .36″ falling since the first – 2014 to date is the 13th driest.

SUMMER 2014 ONE OF THE COOLEST EVER

Since June 1st the average temperature of 71.3° is among the coolest 9% on record and ranks #13 all-time.  More nights have fallen into the 50s (and 40s outlying) in 10 summers.  Rainfall, despite the lack of it so far in August, is still doing well at 10.50″ – the normal through August 15th.

ADVERTISED PATTERN CHANGE

A change in the pattern is evolving this week – keeping things somewhat unsettled and warmth building through the week – the warmest air of the season is still looking possible later in the week, I’m posting the NWS Climate Prediction Center’s 6-10 and 8-14 day temp outlook.  We could beat the 88° maximum summer high later this week. Big questing is will we hit 90°?  Thunderstorms will have a say in that.

Heat possible in the eastern US later this week.
