Severe Weather Season May Get Started Next Week

From Chief Meteorologist Craig Carnesi...

What a difference a day makes. Yesterday we were in the middle and upper 90s, today, middle 70s. Light showers have passed through the area as well. Unfortunately the rain has looked more impressive on radar than from the ground. Most if not all of the precipitation on Triple Doppler radar today has been what you call "virga," or rain that evaporates before reaching the ground. With the very dry air at the surface the rain just can't make the journey from the clouds to the ground.
In the short term rain chances will remain in the forecast through Saturday. That's the good news. I expect us to actually see some rain at the ground as well before all is said and done. We could see a couple of isolated thunderstorms as well beginning tonight. The sub-tropical jet stream has set-up above us. Periodic disturbances will pass and create enough lift for a couple of storms, nothing severe is expected this week.
Next week on the other hand, things could get a little dicey. Sunday looks pleasant with partly cloudy skies and highs back into the middle 70s. A cold front will push through Sunday evening. Monday looks nice as well with partly cloudy skies and highs in the upper 60s.
By Tuesday through Thursday, our old friend, the dryline, could be back in service for the Spring. Strong upper-level dynamics look to setup beginning Tuesday. This could lead to isolated severe thunderstorms beginning Tuesday afternoon and evening.
According to the long range computer models are best chance for strong thunderstorms will be Wednesday night.
Remember we have a long time between now and then and I expect to make changes to this forecast. I just wanted to give you a heads up that Spring weather could be arriving fairly soon.
