Extreme Temperature Diary-May 5, 2019/Week Of Severe Weather Ahead For The United States

Sunday May 5th… Dear Diary. The main purpose of this ongoing blog will be to track United States extreme or record temperatures related to climate change. Any reports I see of ETs will be listed below the main topic of the day. I’ll refer to extreme or record temperatures as ETs (not extraterrestrials).😉

Week Of Severe Weather Ahead For The United States

It’s the first going into the second week of May, so it is the height of the climatological severe weather season for most locations from the central and southern Plains into the Southeast. The pattern this week will be prime for severe storms with the ever present chance for tornadoes in the warm sector of the next powerful system to exit the Southwest and enter the Plains. The only aspect of the synoptic situation coming up this week that is on my climate change radar is how amplified the pattern will be with plenty of warm air aloft near and north of the Arctic Circle, and a warm ridge building towards western Canada:

As I noted last week, the strong system will be exiting the Southwest from Tuesday Into Wednesday:


If a lobe or cold pocket aloft comes out of the Southwest in what meteorologists call a negatively tilt fashion then we will see a significant but probably not unprecedented outbreak of tornadic storms.

At the surface here is one version from the GFS model of the system:

By no means is the associated surface low super deep or strong, but the system will probably produce much wet misery for the flooded, water logged Midwest.

Here is what the Storm Prediction Center anticipates for this week:

You can find any major reports of severe weather in the news section of each of my posts during the week including flood info. If you do live in the Plains or Southeast keep an eye on the sky and stay tuned to The Weather Channel, your local T.V. channel, or the Weather Service for watches, warnings and updates.


Here is some more weather and climate information from Sunday:

(As usual, this will be a fluid post in which more information gets added during the day as it crosses my radar, crediting all who have put it on-line. Items will be archived on this site for posterity. In most instances click on the pictures of each tweet to see each article.)
