Heat Is Still Coming on Strong... More Record Breaking Heat

I don't think it would be fair to describe this heat as anything less than a full summer like pattern. We have a massive ridge of high pressure controlling our area right now and it is flexing it's muscles today. We tied a record high temperature today that was set 116 years ago in as we soared into the mid 90s.




What you may not want to hear is the more records may fall.


Forecast Discussion


The upper level ridge over us is not something that traditionally graces our area in the spring, but this is a full summer like pattern. You can actually see how this big upper level high pressure is the dominating force again in our area for the next 7 days.


GFS Flow At 6 Miles Above The Ground Today

Note, the big high pressure over our area forcing the air to rise up and over our area.




GFS Flow At 6 Miles Above The Ground Wednesday

Notice how the ridge has flattened a little bit. That means the sinking air under that ridge will not be as pronounced and an isolated t-storm is possible mid week.




GFS Flow At 6 Miles Above The Ground Today

Once again by Friday, we see our massive ridge of high pressure re-establishing itself. So very hot conditions will return by late in the week.



This is really the oscillation that we will see in the short term as we the ridge strengthens and weakens. When it is strong, there is tons of sinking air resulting lots of sunshine and major heat. When the ridge flattens, the amount of sinking air lessens and there are more clouds, slim t-shower chances, and not quite as hot temperatures.


Extended Forecast


Tonight will be very warm under mostly clear skies. Our temperatures will only fall to about 74.




The record high tomorrow is 94 set in 1937 and I think we will tie or beat that record. I have mostly sunny skies with a record breaking high of 95.




Finally, we will see a slight increase in our storm chances on Wednesday, then the ridge re-establishes itself pushing highs back into the mid 90s for Friday and Saturday. On Sunday / Monday, the ridge will flatten and the mid level high will weaken a little allowing another some chance of t-storm. The good news is I see no flooding rains in our near future.

Near Or Above Record Heat This Holiday Weekend

Well many of you asked for sunshine and warmer conditions and let me just say it will be here in force shortly. Many records are in danger of falling this weekend... it is going to be that hot!


For a good discussion on why it is getting warmer you can view my previous blog entry here...




Records That Could Fall...


For Saturday, all of our records are safe but Sunday and Monday are different animals. Here are some of the records for the weekend.

Full Extended Forecast


Saturday is the most iffy of the weekend days. Skies will be mostly cloudy, but with the high clouds in the afternoon I think we will still get through and warm us into the mid 80s. Sunday the flames fire as we high 95 under mostly sunny skies and on Monday I do think we will break that record with highs in the mid 90s.


Holiday Forecast 


The heat should hold through early next week then some moderating by the later part of the week.
