WARMING UP for late week!

Ok folks, not really to much change from earlier GFS models runs though only minor thing is that the GFS has been playing around on/off with the idea of a thermal low off the WA coast for late week and also providing maybe a chance of convection somewhere over the WA coast. But other than that, it appears that a VERY WARM ridge looks to be with us for later this week into possibly the July 4th holiday. So for what the models are worth, should see a gradual warming trend through Wed with highs in the low-mid 70`s under mostly sunny skies with maybe some minor low clouds at the WA coast as flow aloft will still be and is shown to generally be near westerly flow. Ah, but then comes Thurs/Fri(see 12zWRF 5pm Thurs image). This is when thicknesses/upper level heights really rise up with thicknesses near or at 570meters and 500mb heights in the lower 580`sdm with light southerly surface flow. And for what the WRF model has been showing, looks like the 'heat' is on with highs in the mid-upper 80`s Thurs and upper 80`s to perhaps lower 90`s Friday. However and while 12MRF-MOS is warm, it shows mid 80`s for both days just mentioned. Could be just as WARM for Sat as well, with highs in the upper 80`s to maybe right at 90. Looks like we cool temperatures down for Sunday into Monday with highs back near and or low 70`s with chance of showers as large trough looks to dip down over the PNW.

12zGEM/ 12zEURO also show ridging for later in the week, but juts like the GFS, it appears it`s more of a surface ridge as isobars are not all that amplified aloft and actually kind of flat so to speak, but we do still appear to maintain warm ridge with high
thicknesses and upper level heights. So for it`s worth, it looks like it could be a nice night to see the fireworks Sat night. You all will have to see as I will be in Ohio later this week through early next week.
