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
Here is one snapshot from this morning's NAM run, depicting the precipitation it predicts for Saturday between 1 and 7 p.m. ET. The rain/snow line should be close to the Pennsylvania-Maryland border.
it appears a storm will form the Southeast and trek toward eastern New England this weekend. Current models suggest this will turn into a mostly rain event in the I-95 corridor...
This map shows a draft of our starting time lines and expected accumulation from tomorrow's quick-moving East Coast storm.
A storm that has brought hardship and danger to parts of Texas and Arkansas with an assortment of ice and snow will send a swath of snow northeastward today and tonight. Here is a map showing our overall estimates as of 10 a.m. ET:
That could lead to tough travel at the end of the weekend. This map for Sunday at 7 p.m. ET shows where those troubles could be (north of the line with the label "snow rain line.")
This table shows the ensemble means for the next two weeks at Philadelphia: It suggests that whereas it does turn cold, any snowfall looks quite limited.
