Here is what we are paying attention to this evening and the next 48 hours from this afternoon’s NWS Forecast.
...There is a Slight Risk of excessive rainfall over parts of the Southern High Plains through Tuesday morning... ...There are Frost Advisories and Freeze Warnings in effect over portions of the interior Northeast as well as coastal Maine tonight...
Continuation of the NWS Short Range Forecast (It is updated twice a day and these updates can be found here.
A weak bit of shortwave energy will support the development of showers and thunderstorms over portions of the Southern Plains tonight, where a Slight Risk of excessive rainfall is in effect due to potential within especially potent thunderstorms. The shortwave is then forecast to spread into the Middle Mississippi Valley and Midwest on Tuesday. The shortwave will merge with and amplify a broad upper-level trough descending over the Plains and Mississippi Valley. A cold front is forecast to sweep through the Northern/Central Plains on Tuesday and become the focus for moderate to heavy rainfall and thunderstorms over the Midwest Tuesday night into Wednesday. Thunderstorm activity is then expected to shift into the Ohio Valley and the Southeast by Wednesday night. Scattered to isolated showers and thunderstorms may form around a stationary front draped across the Florida Panhandle over the next couple of days. Temperatures are expected to rise well above normal over parts of the Upper Midwest and Northern/Central Plains on Tuesday out ahead of the strong cold front and then dropping below normal after the frontal passage on Wednesday. Continued ridging in the West will contribute to well above normal temperatures, especially over the Northwest. Frost Advisories and Freeze warnings are in effect over portions of the interior Northeast and coastal Maine tonight as high pressure builds over southern Quebec and a cold front departs into the western Atlantic. Things warm up in the Northeast by Wednesday as the powerful low pressure system causing unsettled weather over the Midwest approaches.

Some Intermediate-Term Outlooks
Links to “Outlook” maps and discussions for three time periods. Days 6 – 10, Days 8 – 14, and Weeks 3 and 4. An outlook differs from a forecast based on how NOAA uses these terms in that an “outlook” presents information from deviation from normal and the likelihood of these deviations.
You have to click on the links because they do not update automatically and I do not want to have stale images in the article. But it is not difficult to click on a link and you get a large image plus a discussion. On Fridays in a separate article, we will show the images and provide a link in this article that article. But remember what you will see is the images as of Friday. But here you can get the current images simply by clicking on them. Then hit the return arrow at the upper left of your screen to return to the article. You will not find this information easily anywhere else.
Right now you can find these maps here (We show them every Friday there but you can click above and find them).
