Monday 8:30 AM
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
When we look more closely, we see a variety of disturbances embedded in the main current, each capable of temporarily increasing or cutting off the chance of snow. This map shows the setup:
This map shows the circulation around the offshore storm and a larger but less intense storm moving into the Great Lakes. With this sprawling storm likely to be in the region for several days, the weather can vary widely.
...speculation about a snowstorm Monday or Tuesday, and one is still possible. However, timing and placement remain elusive. This map shows the GFS ensemble mean "solution" for Tuesday morning showing snow just off the New England coast. Watch this story evolve on accuweather.com all weekend.
As we look father out this month, it looks cold for the Great Lakes and Northeast (as well as deep into the South) in the middle of next week but milder the following week. This map, for next Wednesday, shows a cold flow from way north in Canada.
A few tornadoes can also occur, especially from Mississippi and Alabama to Kentucky. This map shows the areas of potential severe weather through tonight as forecast by the NWS Storm Prediction Center.
