Cooling showers today, and a nice weekend set-up

Showers and storms will again come through today, this time doing the trick to keep us under the 90-degree mark and ending our heat wave. By next week, the heat will be a fading memory-- some may even feel chilly in the morning. Have a look...

A good Friday to one and all!

Today we will get another batch of showers and storms coming in, courtesy of that rather weak frontal boundary that we've been discussing the past few days. Don't expect a whole lot to come of it, but it will do the trick to keep us out of the 90s for a change. Here's what the WRF is showing for today:

WRF - Rainfall - Friday 2pm WRF - 700mb Humidity - Friday 2pm

Judging from these model products, we'll be looking at the I-79 corridor as the best target for most of the showers, which is reasonable since the front will be nearer to there during the prime heating hours of the day. The Relative Humidity map on the right-hand side implies that skies will be improving from west-to-east later in the day, though I suspect it may take until Saturday to get all the sunny goodness back. No matter, we want it on the weekend anyway. As with any event in this kind of heat, most showers will come with thunder, but these are still expected to be a refreshing nuisance and not much more.

The weekend's weather holds pleasant weather for us-- a little cooler and with sunshine. Sunday itself will get warm again (you never can hold down the temperatures for long if the Sun stays high and clear). The interesting stuff will actually be happening around us. Right now there's a tropical disturbance in the Gulf of Mexico that may develop into our 4th tropical system of the season (which is quite early to be on #4, more on that below). This area of low pressure, regardless of whether or not it becomes "Debby", will be moving across Florida and up the east coast. Far away from us, it will meet up with a strengthening storm system over New England. Here's what the GFS is showing:

GFS - Saturday PM GFS - Wednesday PM

If any of you have read the book The Perfect Storm or now the story, you know that tropical systems can be absorbed by 'regular' low pressure systems when they reach the north Atlantic, and this is precisely what looks like will happen next week. The corresponding jolt of energy will allow this system to pull in even more Canadian air on the back-side of it-- and that's where we are. Check out what happens to our temperatures next week:

GFS - Max Temps - Sunday GFS - Max Temps - Monday GFS - Max Temps - Tuesday

So who's up for a 20-degree drop in temperature? (I doubt we'll actually get that big of a difference, but it would be nice!)

---Tropical Tangent---

Eyes are on the Gulf of Mexico for the possible development of "Debby", but off in irrelevant-land (otherwise known as the central Atlantic) we actually scored our first official Hurricane of the season yesterday, and the name is "Chris".

NHC - "Chris" - Track Unisys - 2012 Storm Tracks

 Harmless and meaningless, but the first hurricane nonetheless. Perhaps this storm will also get absorbed into the large area of low pressure over the Canadian Maritimes this week ;-)
