Pattern Change: From Cold To Severe Weather
Winter time cold weather just doesn’t seem to want to leave our area even though the calendar has flipped into April.
This shot of cold and rainy weather will follow up on what was a colder than average March across most of our area. March saw Fayetteville register the 9th coldest March on record and the 41st coldest March in Fort Smith.
When the NAO is in the negative phase pushes the jet stream, and cold weather, from the north to the south. The NAO is forecast to eventually turn positive allowing for warmer temps and the return of an active and stormy weather pattern.
We are starting to see signs that the overall pattern will start to change from cold to warm and active. This is the 6 to 10 day outlook from the Climate Prediction Center showing those above average temperatures.
The severe weather season has been off to a very slow start with only 15 tornadoes reported nationwide in March. The monthly tornado average in March for the United States is 98 tornadoes.
What has been a very quiet early spring will likely turn into an active severe weather season by the second week of April.
