Wet rush hour marks the start of soaked weekend

3:50 PM
The rain is here and it is not going to be stopping any time soon through this weekend, which will be a perfect time to catch up on some movies, a good book, or perhaps finally conquer a very difficult video game.  What ever you do this weekend, it likely will not be done [...]

Be thankful for the warm conditions, winter is on the way

2:48 PM
The relatively warm conditions that the Philadelphia and New York City metropolitan areas have experienced and will continue to experience up until Thanksgiving, better be enjoyed to the highest degree because significant changes are on the way.
The last time I was able to post several days ago, I detailed my ideas on what to [...]

Pattern becomes congested, cooler conditions on the way

5:15 AM
The upper low that had dominated the weather conditions over the Plains and Mississippi Valley for several days has been ejected to the east and is rapidly weakening.
The remnant short wave trough over the Ohio Valley is still pulling a great deal of moisture to the north into the Southeast, Mid Atlantic, and Northeast. [...]

Strong upper low influences the region

8:45 AM
The pattern this morning is is dominated by two key features.  A strong trough over the Great Lakes and an upper low over the central Plains.
The upper trough over the Great Lakes is still centered to the west of the region, which means a southwesterly flow remains over the Mid Atlantic.  As a result, [...]

Fall conditions return for the weekend

5:15 AM
A cold front will continue to slowly slide off the coast this afternoon as a trough over the Great Lakes moves towards New England.  The cold front will initially stall over the coastal waters this morning, however as the upper level trough lifts to the northeast, upper level winds will shift to the west [...]

Evening Thoughts- Heavy rain and maybe more

9:58 PM
Once again, there is a lot to talk about this evening in terms of the approaching cold front, the associated upper level trough, and we can’t forget Hurricane Bill.
Hurricane Bill as of 5 PM this afternoon has weakened into a category 3 hurricane, however this is in relative terms compared to earlier strength.  Hurricane [...]

The war begins

5:15 AM
A war is about to begin over the Mid Atlantic and Great Lakes that will pit two volatile air masses against each other.  Over the Southeast and Gulf Coast, a hot, humid, and unstable air mass is building and heading north while over eastern Canada; cool, dry air is poised to dive south.  The [...]

Weak high pressure protects forecast area

5:15 AM
The disturbance that brought rain to much of the coast yesterday morning is now well to the northeast of the region as the short wave trough begins to lift into the Canadian Maritimes.  This morning the trough axis is over central Pennsylvania and will continue to slide to the east-northeast over the next 48 [...]

The set up of the battle ground

5:15 AM
Over the next three days, the stage will be set for a battle between relatively cool, dry Canadian air to the north and west and a hot, humid, unstable tropical air mass to the south and east.  Over the forecast area, a stationary boundary will waver north and south each day with various impacts [...]

The broken record continues

5:15 AM
The upper level trough over the eastern half of Canada continues to act like a pendulum swinging back and forth through the Great Lakes and Northeast.  After another strong cold front yesterday afternoon, the pendulum is swinging back to the west, which will give a break to the forecast area from stormy conditions.
Through early [...]
