monthly climate summary

The tumultuous weather of May calmed somewhat with the transition to June, the first month of climatological summer. Despite the seasonal switch, however, there was still plenty of unsettled weather in store for Oklahoma. Western Oklahoma managed to dry out just enough to see the winter wheat harvest make significant advances by the end of the month. Other areas continued to see an active weather pattern with heavy rains, large hail, severe winds, and even tornadoes.

Tornadoes and flooding battled it out for Oklahoma’s top weather headline during May 2019, with both combatants bringing mayhem and misery to the state. The scope and scale of the weather disasters prompted Gov. Kevin Stitt to declare a State of Emergency for all 77 counties. According to reports from the Oklahoma Department of Emergency Management, at least six fatalities and 118 injuries were attributed to the flooding and severe weather.

Following a few brief glimpses in March, spring finally arrived in earnest during April. The month was wet for most and warm for all, and came complete with all the spring severe weather hazards Oklahomans are accustomed to. The state’s first official tornado of 2019 struck on the 17th near Shattuck. The twister, rated an EF1 by the National Weather Service (NWS), damaged homes, sheds, trees and fences. Baseball size hail fell near Selman in Harper County that same day, and near Gould in Harmon County on April 3.

Spring failed to gain a toehold during March, a month that both began and finished with a healthy dose of winter. A powerful cold front plowed through the Southern Plains over the first few days of the month and brought a bit of snow, a bit of ice, and a generous portion of frigid weather. Wind chills fell below zero over much of the state, and as low as minus 12 degrees in the Panhandle. Snow totals were generally light – less than an inch in most areas – although Forgan and Claremore reported 4 and 5 inches, respectively.

Drought, fire danger, floods, severe storms, multiple bouts with freezing rain, and even a good old fashioned Plains snowstorm – Oklahoma’s weather had a little bit of everything during February. Frequent incursions of arctic air kept Oklahomans guessing what to wear from day to day, although choices from the spring wardrobe were rare. A round of severe storms marched across the state Feb. 6-7 ahead of an arctic front. Hail, damaging winds and flash flooding were reported with the storms, followed by a batch of freezing rain behind the front.

The weather was a bit confused in Oklahoma during January. The first half of the month was on the warm and wet side of normal, while the second half was dominated by short, intense periods of dry winter’s chill. The state received an average of 1.86 inches of precipitation from January 1-12, but only 0.31 inches throughout the rest of the month – the 5th wettest and 25th driest such periods on record, respectively. The month’s biggest thrill came in the form of a winter storm on January 3, with freezing rain, sleet and snow falling across much of the state.

Three soaking storm systems brought much needed precipitation to the state, ending a run of up to 78 days without significant moisture for much of northern and western Oklahoma. Like last year at this time, the winter wheat crop was clamoring for a good drink of water, and fire danger was increasing with each dry, windy day. Between the three storms, virtually all areas of the state saw relief by the end of the month. The most significant storm struck just after Christmas Day and dumped 1-3 inches of rain across a good portion of the state.

Much of Oklahoma’s weather was downright boring during November – cold and dry with a few warm days in between. Despite that monotony, Mother Nature still managed to sneak in a couple of stretches of exciting weather. The first bout struck on the 12th with Oklahoma’s first significant winter storm of the season. Snow fell across the northwestern half of the state and dropped as much as 5 inches of snow. While most of it melted as it fell, enough accumulated across the far northwest to prompt a winter storm warning from the National Weather Service (NWS).

Oklahomans experienced the gamut of their state’s annual weather hazards during October. Flooding rains, extreme heat, an arctic blast, the season’s first snow, severe thunderstorms, and a slew of tornadoes – all were present during an active weather month. A weak tornado formed near Fairfax on Oct. 7, damaging roofs and power poles. Tornadoes struck again just after daybreak on Oct. 9, forming along the leading edge of a squall line moving across central Oklahoma.
