Today’s Northeast weather discussion…
The surface chart shows the cold front approaching from the north, this will move through today into early tomorrow, bringing gusty winds, that could gust 30-near 40 mph at times. The front is moisture starved, so a lot of rain isn’t likely, but unlike the last few frontal passages, this time it looks like everyone will see at least some rain; Any rain is welcome at this point.
High
pressure will build in for Saturday into Sunday. We should see a lot of sun for
Saturday, but it will be rather cool. Then for Sunday we start out dry, but a
frontal system with as warm front will be approaching and moving through on Sunday
and Veterans Day Monday, bringing the chance for scattered rain showers, and
some mountain snow showers.
Tuesday and Wednesday
will see high pressure overhead, temperatures will once again become above
average for this point in November, the region should be dry during this time.
Then Wednesday night and Thursday another system will approach and move
through, this will bring a chance for more in the way of widespread rain that
could be heavy at times, with amounts a bit higher than we’ve seen the last
several weeks, it won’t be a drought buster, but it could put a dent in things.
For Friday we will have to see if a
coastal low could develop along the frontal boundary.
Rafael
Earlier
today Rafael regained Category 3 status, with max sustained winds of 120 mph.
Since then, he has weakened back to a Category 2 hurricane, but he has strengthened
again. He now has max sustained winds of 110 mph, central pressure at 961 mb,
tracking west at 9 mph.
The ocean
heat content in this part of the GOM is very high. So, with the other factors overall
favorable, he intensified. The steering winds are weak, so he should continue
to meander and could even make a loop over the western and central GOM. Rafael
has used his bag of tricks very well; this is making him unpredictable. But the
current set-up favors him staying out over the GOM for the next few days, where
he should slowly weaken over the weekend into next week. But with his erratic
nature, the northern Gulf Coast and even Florida should keep an eye on him. Even
with him likely being a fish storm, rip currents and high surf will be an issue
for the Gulf Coast.
Drought
I am happy
to see some of y’all are commenting and asking questions on the blog. There was
a very good one that was asked on yesterdays’ drought outlook post. They asked
when is the current pattern going to change? Here is the answer I gave.
Every
pattern does change at some point, but the steps leading up to the change can
be slow to come in a persistent pattern like we're in now. We will have chances
for rainfall going forward, this pattern is going to make widespread soaking
rain events very hard to come-by. Rafael should stay in the Gulf, but if
Rafael does end up making a landfall on the Gulf Coast, he would get tangled up
in the progressive pattern of quick moving fronts. Some of that moisture could
bring us some rain into our region, but that isn’t a sure thing. I just don’t
see this overall pattern changing for the entire month of November. There are
signs of some kind of pattern flip once we get into December. But we will have
to see how that pans out. With the overall temperatures looking to stay overall
above average for the next several weeks, I expect the drought will be getting
worse.
What happened to the mid November flip?
ReplyDeleteThe La Nina is taking more time, than I thought it would as well as this negative PDO that keeps hanging on.
DeleteIt looks to me like a pattern change starting Tuesday??
DeleteI don’t see any long-lasting pattern change, The subtropical and polar Jet look to keep this up and down pattern continuing for at least a couple of weeks. So, we will see a couple of mild days followed by a few cooler days. With the strong polar vortex, I don’t see any real cold entering the pattern until we get into December. During the 2nd part of November, we could see more chances for some rain events. But the progressive nature of the setup means these would be faster moving systems, along with the risk for some weak coastal systems developing. But right now, they don’t look to be big deals based on how the MJO and other teleconnections are indicating. I will be touching on this in part 2 of the winter outlook, which I’m currently working on.
