Oklahoma had a really hot summer. The average temperature was 83.1, more than 2 degrees above the long-term average. From July 18th through Aug. 9th, only one day had a high temperature of less than 100, and on that day (Aug. 5), it was 99! Today, however, Oklahoma City had its earliest subfreezing reading ever! However, even though it is chilly out this morning, the chill will soon be out of the area. And, in the Northeast, where a couple of chilly shots are coming in this week, next week could very well be milder.
It is national metric week, and supporters encourage people to jump in with both feet and support the metric system every inch of the way.
In weather forecasting we jump back and forth with units, but I think the main yardstick of public acceptance is people still want their temperatures in fahrenheit. There is a good reason for this. In our common experience, the coldest day in winter is often around zero while the hottest day in summer approaches 100. A zero to 100 scale is quite attractive. In contrast, people get out the bug killer when they see millipeders or centipeders in their homes! I mean, suppose gram is coming over. One of the main attractions of metric units is how basic measurements get decimated.
Today is dry throughout the Northeast and most of the Great Lakes region, but people wonder if the weather will stay the same furlong. Will it be okay for yardwork? Since it will be dry today, things look good. The same applies for construction crews who have to install footers. It will be dry across the 378 kilometers between Chicago and Detroit today. Rain will spread through the I-95 corridor later today and tonight. We estimate that the many areas will get less than a quarter of an inch of rain (less than a centimeter). It is often difficult to fathom exactly how much rain a storm will deliver when it is just in the formative stages like this one, but by most measures, it seems there will be on-and-off rain and drizzle from gray skies.
Sometime we get snow showers across parts of the Great Lakes and Northeast in mid-October. However, results from various metrics studies suggest we could wind up with a foot in our mouth if we give such predictions more than an ounce of trust at this point. In fact, temperatures could inch higher next weekend. Want updates? Follow the liter, AccuWeather.com
A storm strengthening off the Middle Atlantic coast will cause episodes of rain and cool gusty winds from Maryland to Maine. The heaviest rain today is focused on the Washington, D.C., to New York City area. Later tonight and tomorrow, the heaviest rain and strongest winds (gusts of 30-40 mph) should spread northeastward across New England. As the storm slowly departs, the weather will improve from southwest to northeast. This map shows the circulation around the storm as of 9 a.m. ET.
The reason for this is a growing and then stalling storm aloft. This map shows the predicted circulation around the storm on Wednesday evening, showing how the moisture could keep going round and round until the storm leaves.
This mornng, showers were moving across the lower Great Lakes region. A band of thunderstorms developed near Chicago before 6:30 a.m. CT and reached the southwest Michigan shoreline an hour later (8:30 a.m. ET). The following maps show the shower zone and Chicago area lightning.
The tropics have been more active recently. This map shows various entities that area being tracked and analyzed. Hurricane Gonzalo stands out clearly.
A couple of days ago, the storm entering the East had a stronger circulation than it does now. Here is the pressure analysis from earlier this morning. Several minor disturbance can be seen, and trough lines representing those have been sketched on the map. Note that there is little difference in temperature from western Pennsylvania to Wisconsin.
The rain band is only 100-200 miles wide, but it is moving slowly. This map shows its location at 10 a.m. today. Once the main rain band passes, it won't be quite as warm as it was when the rain started. However, by mid-October standard, it will still be mild.
