Nice Wx Week

For the middle of November, the wx this week will most certainly cooperate.  Once this rather sharp cold front passes through later this evening, the wx will be dominated by high pressure for the remainder of the week into this weekend.  And this is quite the front...it doesn't have great upper level dynamics associated with it like it did out in the mid-west as it progressed across the CONUS; however, there will still be quite a bit of showery rains and gusty winds 12 hrs either side of the frontal passage through KMDT.  Here is a snapshot of the temps on either side of the front as progged by the NAM...
Note the 24 hour temp change with the passage of the front in the mid-west!

The heaviest of the rain appears to want to fall early Tuesday morning and if you take the Rapid Refresh Model literally, the morning commute with be one with heavy showers to contend!
But once this cold fronts progresses through the east, high pressure will rule the roost.  Look at the forecast modeled lows for Wednesday morning...quite a difference from this mild Monday morning!
Also note the uniformity of the morning low temps across most of the CONUS!  Hence the term...air mass!  Here is the GFS' take on the pressures at the surface for Saturday morning.  Looks like a typical fall regime with clear cool nights and mornings with moderating temps during the day with relatively bright sunshine.  do remember that we are essentially only ONE MONTH from the lowest sun angle we see at our latitude!  So don't rely too heavily on the warming power of the sun at this time of year...although Ol' Sol can work his magic!
Eventually, that 1035 mb high will move NE away from the US and allow some unsettled wx to gather over the southern states that must be watched for Thanksgiving week.  The Euro actually has yet another coastal storm progged for the early part of next week...and the pattern suggests this solution could verify.  At the very least, it must certainly be monitored for devilish developments which could make the wx in these parts rather interesting a day or 2 either side of Turkey Day!
So there is a quick overview of the wx for the next week.  Once the wx systems come more into line for next week, I'll try to update everyone with how the sensible wx might respond.  In the meantime, more about the fiscal cliff, the losing Eagles, and the solar eclipse in Australia.  Yes...keep your eyes on the internet to see some neat reports from the total solar eclipse over NE Australia and the Great Barrier Reef!
Or you can monitor how Congress and the newly re-elected president want to tackle this so called US Fiscal Clif...
Not to be confused with what my buddy saw me eating today, called it...my "Fiscal Clif Bar"...made me laugh!  Maybe you had to be there, but I thought it to be very humorous!
OK...enough for now...so since I mentioned "Eclipse", I'll leave you with a cut from one of my favorite albums of all time...released in March of 1973 and sold over 15,000,000 copies in the US; Pink Floyd's Dark Side of the Moon.  The final cut (not another one of their albums) is titled Eclipse...and I think you might like!

Enjoy....the mid-week, the cold frontal passage, and this incredible closing song!

AA:  Cold front passes through overnight Monday into early Tuesday with some rain and wind...then nice seasonable wx into the weekend.  Watching a storm for Thanksgiving week....?
