As of now there is a high wind warning for parts of eastern and southeastern Massachusetts late tonight and into the first half of Wednesday. The map shows which areas will experience the strongest winds. wind warning.jpg If you are not in the warning area, you will still have strong winds. There will be downed trees and power outages from this burst of wind.

When do you think was the last time Boston had over an inch of rain? You might be surprised to know you have to go back to August 9th when 1.62 inches of rain was recorded at Logan Airport. It's been close to 4 months of very dry conditions and while that makes the upcoming rain storm a good thing, the timing is anything but good. The image below shows all the watches, warnings and advisories currently in place for much of the east. This is subject to change several times each day and I will be updating it often.warnings right now.jpg

I'll be updating the forecast for the storm on Twitter at @growingwisdom Please follow me there. Feel free to comment or ask questions too.

Before I get to the details of the forecast, let me talk about the traffic for a minute. Tuesday afternoon through Tuesday evening has become one of the busiest periods to leave the area, now rivaling Wednesday. Keep this in mind when making plans on exactly when to hit the roads. Wednesday morning is usually a very light traffic day, with the bulk of the cars hitting the road after noon. The traffic also tends to die off a bit earlier Wednesday evening than you might expect.

Now let's put the upcoming storm on top of what we know about the traffic. I don't expect any rain today for the most of the daylight hours. Take a look at the map to the left, you can click it to make it bigger. This is a projected radar for 8PM. At that time rain will have broken out across much of Connecticut and down through New York City. If you are leaving Boston to drive south, you are going to hit rain, but not any wintry weather.

The next image shows a wider shot of about the same time period. Notice the heavy rain down much of the Atlantic seaboard. On the western side of the rain back through Pittsburgh, parts of Ohio and western New York it will be snowing. total rain and snow.png Some of the snow will be heavy and wet and cause power outages.

Overnight, the peak of the wind and rain will be affecting southern and central New England. Rain will come down heavy at times and somewhere between 1 and 3 inches of water will fall. Winds will be strong and a high wind advisory is up for much of the area for Tuesday night through Wednesday night. The radar below shows how the heavy rain will be positioned around 2 AM tomorrow..

Since today is going to be dry and not too cold, if you can safely clean out your gutters I highly recommend doing so. If you normally don't have a problem with water coming in, don't worry about it, but if you are like me, the gutters overflow into the basement and I don't need that hastle on top of cooking for 14.

Wednesday will start very wet and windy, but the storm is moving so fast, I expect the rain to be over before sunset. This is good news if you need to travel Wednesday evening as the rain will be moving north rapidily. Across New York and points further south, the rain will end Wednesday morning quite early. The next map shows the projected radar around sunset Wednesday. Notice most of the rain is over by then.

The final map below shows how much rain or water equivalent of snow will fall from this storm over the next three days. Notice it's a very even 1 to 3 inch amount for a huge area of the east.

As the storm ends, colder air will wrap in and there could be a quick flurry, but I am not expecting any significant snow at all from this system.

Temperatures have been increasing much of the night and continue to rise through the day on Wednesday. I expect many areas to reach the upper 50s to mid 60s and you will actually feel some humidity in the air. It's an amazing atmospheric turnaround from the arctic air currently departing.

The rest of the holiday weekend looks dry with cold conditions for Thanksgiving. Highs on Turkey Day will barely hit the freezing mark with a repeat on Friday. We will have a slightly less cold day Saturday and Sunday highs should rebound close to 40F with more clouds.

Around the House This Week
I know some of you are already thinking about Christmas trees. Did you ever consider there are great trees you can add to the landscape that make great Christmas trees? Even if you don't decorate the tree, it will still be a wonderful addition in the landscape.
