Omega Pattern setting up- warm weather through the weekend!

April 12, 2016: Hard to beat sunny, quiet weather around the region! It could be a little warmer, as temperatures in the low 50’s is around 10 degrees below average for this time of year. Luckily, warmer weather is building in over the rest of the week thanks to an “omega blocking pattern” setting up by this weekend.

Jet stream pattern for this weekend

By the end of the week, the jet stream will feature two deep dips southward, one over the Rockies and the second over the Atlantic.  In between, a strong area of high pressure builds in over teh Midwest. This pattern resembles the Greek letter omega (Ω) , and results in the weather staying warm and quiet over the middle of the country, with wet and cool weather in the West and over the Atlantic.

We’ll have sunny and warm weather for several days in a row, as this pattern “blocks” any new weather systems from entering/exiting, so look for more wonderful spring weather at the end of the week!
