13 June '26: Happy Saturday! :)



Let's ask wt360's "SUNNY" about the big flip-flop in the latter half of June. CLICK ON IMAGES FOR A LARGER VIEW

LOG 1 A

The front half of June was predominantly warmer and drier than last year benefiting hot seasonal categories that slowed a bit with the coolest U.S. May in 5 years. This led to a pent up demand surge in hot categories like AC, pool supplies, allergy medications and cold beverages. But, the back half of June looks to trend much cooler than last year's record hot end to June with the coolest conditions in 3 years and wettest in 8 years. This will dampen demand for Father's Day and 4th of July day sales.

LOG 2

Much needed rainfall will alleviate some drought conditions in the Eastern U.S. The U.S. Corn Belt (Iowa to Ohio) has benefited from a wetter pattern this Spring which in part sent corn prices plummeting from $4.82 in Mid-May to now $4.12 here in Mid-June.

LOG 3

Last Week (7-13 June) across the World shows the U.S. trending +2.3F warmer than last year, warmest in 5 years and 2nd warmest in 41 years. Hot 90F days were also up +35% over LY, most in 5 years and 5th most in 41 years. Rainfall down -12% vs Last Year but still 18th most in 41 years. Overall, these were very favorable trends for higher demand for seasonal categories like AC, pool chemicals, auto batteries and cold beverages. Canada was warmer, a plus, but also much wetter, a negative for seasonal sales. Continued cooler and much wetter across the U.K. and Europe which suppresses footfall.

LOG 4

The week ahead Severe Weather outlook shows a high risk Saturday in the Central U.S. spreading to the East Coast by Sunday. Another round of severe weather next week from the Midwest to the Northeast as the strong cold front ushers in much cooler weather.

LOG 5

A new feature with the wt360 interactive maps is a FUTURE 18-HOUR RADAR forecast. This Saturday morning's forecast shows the severe weather exploding from Oklahoma to Illinois late this evening. Yes, that's SNOW in the Montana - Wyoming areas.

LOG 6

This Week (14-20 June) prior Father's Day weekend shows the dramatic cool down moving into the Central U.S. with heat building in the West. The U.S. overall will trend -2.1F cooler than last year, coolest in 3 years and 18th warmest in 41 years. Hot 90F days are way down -39% vs last year, least in 3 years and 12th least in 41 years, while rainfall is up +11% vs last year, wettest in 7 years and 9th wettest in 41 years. This will suppress some demand for Father's Day sales and definitely a big slow down for hot Summer categories.

LOG 7Next Week (21-27 June) shows the cool weather expanding to the East Coast with the U.S. trending -3.2F cooler than last year, coolest in 3 years and 14th coolest in 41 years with below average national temperatures. This will slow hot category sales significantly. Hot 90F days nationally are down -50% vs last year's near record heat, fewest in 9 years and 13 fewest in 41 years. Rainfall way up +23% vs last year, most in 3 years and 14th wettest in 41 years.

LOG 8

The World 2-week Temperature Outlook (14-27 Jun) shows the overall much cooler pattern for Canada and the Eastern 2/3rds of the U.S. with hot weather limited to Western North America and the Southeast U.S. The U.S. overall looks to trend the coolest in 3 years and wettest in 8 years. Western Europe also turns much hotter.

LOG 9

The World 2-week Precipitation Outlook (14-27 Jun) shows the much wetter pattern for the Eastern half of the U.S. and across Southern Brazil. Europe turns much drier overall. Excessively wet across Southern China.
