Record-breaking Summer-like Warmth to Persist

After a "cooler" weekend, with highs only in the mid to upper 70's, and with scattered showers and thunderstorms.  In fact, compared to Thursday and Wednesday, these days were not near as far above average.  This is all about to change, as an incredible jet streak that has remained over the Pacific Ocean for the last week, is finally moving into the Western trough, which is the source of the stormy weather out west.  As the jet streak moves into the trough, it will cause an incredible deepening of the storm system, so deep in fact that the entire trough will break away from the jet stream in the form of a cut-off low.  Before this happens, the extreme deepening of the trough will cause the ridge over the east will amplify considerably, causing yet another surge of extremely warm air into the region.  In fact, this next surge of warm air will be even greater than the first surge back on last Wednesday, when temperatures first hit the lower 80's.  Tomorrow, I expect that after a relatively warm morning in the lower 60's, along with dense fog in areas, temperatures will warm considerably into the low and possibly even mid-80's, depending on the degree of cloud cover, which is all dependent on thunderstorm development in the afternoon tomorrow.  Either way, it is likely that temperatures will reach into the lower 80's, along with ample sunshine and warm southerly winds.  By Tuesday, temperatures have an even greater chance of hitting of the middle 80's, though mid level clouds could keep temperatures in check in the lower 80's.  GFSx model guidance suggests that the incredibly warm temperatures in the 80's will continue into Wednesday, with mid to upper 70's likely on Thursday as the chance of thunderstorms moves in.  By Friday, the closed-low will likely affect the region with widespread showers and thunderstorms, along with temperatures dropping into the upper 60's.  Here's where discrepancies come between model data.  The GFS is suggesting that the storm system will stall much longer in the Central Plains, which will keep warm air flowing into the region through Friday, keeping high temperatures in the middle 70's.  Amazingly, this is coming from a model that is very progressive, which means that normally it would have this system moving out a lot faster than it actually would.  If a progressive computer model is showing a much slower solution than all of the other computer models, more than likely it is the model that is likely to be the most accurate, especially in these types of situations.  Either way, I will keep a close eye on this, because it could mean a greater chance for severe weather come Friday or possibly Saturday.  Keep on checking this blog for further updates.
