Sweet April Showers, Do Spring May Flowers…
Tuesday, April 2nd, 2013
“Sweet April showers
Do spring May flowers”
was a quote from a 1500s poet named Thomas Tusser, who wrote about looking on the bright side of things at life in general. It teaches us patience… getting through those tough times with an optimistic outlook and enjoying the fruits thereafter! Yes, this has been a slow start to Spring 2013 with many seeing temperatures well below average. Temperatures are still running a good 10° to 20° below average in some places East of the Rocky Mountains! Spring has sprung however in a few spots across the country. Take a look at some of the pictures below.
Highs From Average Today
High Temps from average today will be WELL below normal once again for a large chunk of the eastern half of the country. It’ll feel quite a bit more like February rather than early April. This cooler than normal weather seems to be a continuation of what we had during much of March!
Why So Cold?
We’ve been so cold over the last several days/weeks because of a feature known as a “Greenland Blocking High” – this is a ridge of high pressure that has set up over Greenland allowing the cold air from the Arctic regions to keep funneling into the U.S. – Interestingly, the Greenland “Blocking” high that is currently there, is much like the strong “Blocking High” that set up in the eastern part of the country in March 2012 and led to so many record warm temps last year at this time! Greenland is seeing the record warming and significant ice melt this year!
The Greenland blocking high resulted in a fairly persistent trough of low pressure over the northeastern quadrant of the nation through much of March.
Less Severe Weather
Because of this nearly persistent trough of low pressure, severe weather was also held in check. The lack of warmth led to a lack of severe weather outbreaks across the mid-section of the nation and Ohio River Valley. The image below shows the number of severe weather reports for the entire month of March 2013. Interestingly, there were only 17 tornado reports (red dot) for the entire month. An average March sees nearly 80 tornado reports!
More Active Severe Weather March 2012
Because temperatures were so much warmer last year, we were able to invigorate more thunderstorm chances across a larger area. The image below shows the severe weather reports from March 2012, note how far north those tornado reports (red dot) were last year! Also, there were nearly 250 tornado reports in March 2012 (March Avg. = 80)
Jet Stream March 2012
The image below shows the jet stream winds from March of 2012. Note how much different it looks this year compared to last.
April… In Like a Lion?
March 2013 only had 17 tornado reports (March Avg. = 80) and as of yesterday, there were 2 tornado reports for the month of April. Thanks to Leslie Richardon for the image below near Silverton, TX!
We’ve also seen large hail as of late throughout parts of the Central and Southern Plains, some of the biggest ones (Up to softball size) were reported in Texas over the weekend.
Severe Weather Threat Tuesday
The Storm Prediction Center has issued a SLIGHT RISK of severe weather for parts of southern Texas today. Hail and high winds look to be the primary threat, but an isolated tornado can’t be ruled out, especially in far western Texas near Ft. Stockton.
Forecast models suggest quite a bit of rainfall across the Deep South through Wednesday. Some could see 2″ to 4″+ (localized flooding may be possible).
UGH! Yes, there is also some snow potential on the north/northwestern side of the low as it tracks out of the Southwest. It won’t be a blockbuster, but there could be some light accumulations.
The extended outlook April 7th – April 11th calls for warming conditions in the east! Temperatures may actually get above average for a change by the weekend/next week!
Stormier Next Week?
Extended model suggest a little strong storm potential by next week across the middle part of the country. It’ll be interesting to see how the warmer weather and more active pattern plays into our severe weather potential next week.
Average April Tornadoes
By the way, April typically sees 155 tornadoes across the nation. May is the most active month with an average of 276 tornadoes.
Thanks for checking in on this Tuesday, have a great rest of your week!
