March on!


Who's ready for a little warmth? Because it was COLD this weekend. And I griped
about how cold it was at the beginning of March, but I think this was worse
since it came at the end of the month, a full 31 days into climatological spring.
Precariously late in the season for ag folks growing wheat and other winter
crops.

But help (i.e., spring) is on the way. We should see temperatures start to
climb throughout the week into the 70s and 80s just in time for the weekend.

Man, that do look purty! (Okie translation: "Oh my, those temperatures on Friday
look quite lovely. Brilliant!"). And CPC thinks it might last awhile this time.
Cross your fingers, flip a coin, yank all the fuzz off of a caterpillar...
whatever you need to do!

Gotta get excited because March was cold! Not all the time, but it started
frigid and ended downright freezing. Check out the March monthly summary below
for all the gory and poorly written details.

Hopefully, spring has sprung!

March Sees Spring Sparingly
April 1, 2019

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. Another strong front
struck during the last couple of days of March and dropped low temperatures
well below freezing across the northwestern half of the state. The Mesonet site
at Eva recorded a teeth-chattering 16 degrees on March’s final day.

Hail up to the size of baseballs plagued central and eastern Oklahoma
associated with a storm system on the 23rd and 24th. Perhaps the most damaging
March hazard was a windstorm that enveloped the state March 13-14. Winds gusted
to more than 70 mph across western Oklahoma, and 50-60 mph to the east. The
Oklahoma Mesonet recorded 303 instances of wind gusts 58 mph or greater on the
13th, the speed required to trigger a severe thunderstorm warning according to
National Weather Service criteria. There were widespread reports of downed
power lines and trees, and a fire station in Del City lost part of its roof due
to the severe winds.

According to preliminary data from the Oklahoma Mesonet, March fell 3.4 degrees
below normal with a statewide average of 47 degrees. That ranked the month as
the 33rd coolest March since records began in 1895.

The chill during that first week was profound. High temperatures in the
Panhandle failed to reach 20 degrees on March 3-4, more than 30 degrees below
normal. Kenton recorded a low of minus 2 degrees on March 5 for the lowest
temperature of the month. McAlester broke its record low on March 5, falling to
13 degrees. The northwest half of the state spent more than 100 hours below
freezing during March’s first seven days, with 50-90 of those hours below 24
degrees. The southeast half spent 50-90 hours below 32 degrees.

There was a bit of spring heat to satisfy warm weather fans, mostly during the
latter half of the month. Arnett and Woodward reached 87 degrees on the 28th
for the highest mark. The January-March statewide average of 42 degrees was 1.4
degrees below normal, the 58th coolest first three months of the year on record.

The statewide average precipitation total was 2.58 inches, 0.46 inches below
normal and ranked as the 53rd wettest March on record. There was a wide
disparity between rain totals in various regions of the state, however. West
central Oklahoma finished with an average of 2.86 inches, 0.57 inches above
normal for their 21st wettest March on record. The Panhandle was close behind
at 0.54 inches above normal with an average total of 1.97 inches, their 24th
wettest March on record. Meanwhile, the southeast was more than an inch below
normal at 3.12 inches, their 44th driest March. While all of the Mesonet’s 120
stations received at least an inch of rain, the majority ended at a deficit for
the month. Boise City recorded the least with 1.16 inches. Cookson led all
stations with 4.66 inches.

The first three months of the year saw a deficit of 0.22 inches, the 50th
wettest January-March on record.

Following a brief flare up of drought in southwest Oklahoma in late February,
enough precipitation fell to reduce that area back to “abnormally dry”
conditions on the U.S. Drought Monitor report during March.

According to the April outlooks from the Climate Prediction Center (CPC),
chances of that drought returning within the next month are remote. Those
outlooks show increased odds for above normal precipitation across the entire
state during April. Chances are also increased for above normal temperatures
over eastern Oklahoma and the western Panhandle. CPC’s April drought outlook
does not indicate any drought intensification within Oklahoma during April.
