May 2016 Global Weather Summary & Crop Growing Region Roundup

May 2016 U.S. Weather Roundup

Temperatures for the U.S. overall it was the coolest in May in 5 years trending 11th coldest of the past 25+ years (-0.1F below average and -1.3F colder than last year). But it was a month full of wild extremes with record cold frost and freezes in the middle of the month from the Midwest to the Northeast. This did more damage to crops, berries and fruit trees. There was even some light accumulating snow in the Ohio Valley and interior Northeast. Late in the month over the Memorial Day weekend many cities in the Northeast had their first official heat-wave with 3-days over 90F. Some areas had 4 days over 90F with the Newark NJ area setting a record of 96F.

Front half of June looks to be the 3rd driest of the past 25 years in Iowa, Missouri, Georgia and 5th driest in 25 year for Kansas – they’ll welcome so drying out. Texas not so lucky as they look to get off to the wettest start in over 25 years! South Florida remains wet with the risk of some tropical activity as the Caribbean ocean temperatures are 1 to 3F above average.

Temperatures for the front half of the month are cooler than average from Texas to the Ohio Valley while the Southeast is warmer than average with the West Coast cooking in very hot temperatures.

Late June looks to get very hot/dry for much of the country with the hottest driest Summer in 4 years for the U.S. overall.

April 2016 Global Weather Summary

April 2016 is in the weather history books. There were a lot of challenges for businesses and especially farmers around the world.

Here in the U.S. April overall was cooler than last year for the Eastern half of the country with the Northeast the real cool spot, trending coldest and snowiest in 9 years while the other end of the country was the warmest in 25+ years in the Pacific Northwest.

April-blog-1-us-temps_blogThere were several devastating freezes in the East with so much vegetation emerging 3-4 weeks early this year due to the record warm Winter and 2nd Warmest March in 121 years. The 4th -10th was particularly devastating with many days of low temps in the 15F to 28F range with freezes all the way into South Carolina on the 6th and 10th. Many fruit tree farmers in the region are expecting major losses. Temperatures moderated significantly for the later half of the month. The Plains also had some freezes mid-month with patchy frost late in the month in the Midwest.

April-blog-2-us-daily-chart_blog  For the U.S. as a whole April ended up +0.8F warmer than average but -0.7F colder than last year.

April-blog-3-25-yr-temp-chart_blogGlobally there were all sorts of impacts to farmers especially with major freezes in France destroying much of the grapes – not a good year for French wines. Brazil ended up the hottest in over 25+ years with major negative impacts to their Corn Crops that were pollinating right in the middle of a 3-week hot/dry stretch of 90s.

April-blog-4-global-temp-mapRainfall in the U.S. was feast or famine with the Central Plains from Texas to South Dakota getting inundated, especially the Houston area where over 16″ of rain fell during the month. In the Upper Midwest it was the driest in 12 years, the Northeast driest in 6 years. Parts of California had more heavy rain and heavy mountain snow – very unusual for April.

April-blog-5-us-precip_blogDay-by-Day the wettest periods nationally were the 11th, 18th and 30th.

April-blog-6-us-daily-precip-chart_blogDespite the flooding rains in the Central U.S., the U.S. overall still had the driest April in 4 years but still above average.

April-blog-7-precip-25-yr-trendsSnowfall was heaviest in the Northeast and the Rocky Mountains with the national index the most in 3 years and near average.

April-blog-8-snowfall-25-yr-trendsGlobally rainfall was also excessive down in Argentina where it was the wettest in 17 years but in some areas record flooding. The SoyBean harvest was decimated with farmers unable to harvest with many crops lost which sent SoyBean prices soaring to 9 month highs while just to the north Brazil was being scorched with heat and very dry conditions.

April-blog-9-global-rain-map_blogFinally, it is very clear La Niña is forming at warp speed. Compared to this time last year the Pacific Ocean is cooling off very quickly with the Equatorial Pacific starting to show the classic cooler water temperatures associated with La Niña.

April-blog-10-global-ocean-temps_blogWhile NOAA said just a few weeks ago there is a 50% chance of La Nina, got’a love government thinking, in reality all signs point to near 100% certainty of a La Nina with weak conditions by June, moderate by July, strong by late Summer and potentially very strong by late Fall – Winter. Here’s their latest model, common sense and empirical evidence suggest there is no doubt we’re headed for a prolonged 2-year La Nina which bring hot/dry Summers and cold/dry Winters for the U.S. overall.
