Taking a look back at June and the first of three summer months and it had it’s fair share of extremes from record hottest in parts of the West while cool but more impressively, wet over parts of the Cornbelt. While warm and dry Out West, it was cool and wet in and around the Great Lakes and Northeast. Near opposite of May. The Southeast had a very warm spell during the month.

As you can see from the above, the dry and wet ground is really reflective of the temperature anomaly.

With the feedback cycle of increasingly dry ground equalling hotter surface temps, the drought conditions have noticeably worsened over the Pacific Northwest in the past month.

It’s becoming increasingly dry over the Pacific Northwest and it’s here where the focus of heat is and has been whereas where it’s been rather wet of late, well temperatures are nothing to write home about.

It’s been record hot from Vegas to Seattle across to Spokane while highs have been struggling day by day in the 60s around the Great Lakes.

WETTEST JUNE FOR ILLINOIS

June 2015 turned out to be the wettest on record for the state of Illinois, this has gotten things off to a particularly cool start to July and it certainly doesn’t bode well for a hot July.

DROUGHT, HEAT & WILDFIRE PERSISTS/WORSENS IN ALASKA

The drought, heat, wild fire and lack of seasonal snow theme remains up in Alaska. As of Jul 1, Anchorage officially declared a new record for least snow in a year.

June 2015 scraped past June 2013 as the warmest on record in Anchorage.

The below is no coincidence given how warm the waters are up the entire West Coast of North America.

The warm Pacific is the primary driver behind the warmer, drier than normal conditions which have continued to persist for up to 2 years now.

What’s Ahead For July?

With the continuation of the highly amplified record breaking phase 6 into 7 of the MJO and overall drivers currently over the N Hemisphere, there’s no change to the medium to long term idea. Cool looks to remain the rule for much of the country through the majority of July.

CFSv2 weeklies remains with the Plains centred chill through the rest of the month. Note it’s stronger with the chill day 6-10.
