Continuation of the NWS Short Range Forecast (It is updated twice a day and these updates can be found here.
Upper-level energy over the Northeast will move into Southeastern Canada by Monday morning. As the energy departs, lake-effect snow downwind from Lakes Superior, Michigan, Huron, Erie, and Ontario ends late Sunday night. The energy will also produce light rain over parts of the Northeast, ending overnight Sunday. Light snow will also develop over parts of Northern New England, ending by Monday afternoon. The snow will result in reduced visibility and hazardous driving conditions. Meanwhile, a second area of upper-level energy over the Southern California/Southwest will move northeastward to the Ohio Valley by Tuesday, inducing a front along the Central Gulf Coast into the Southeast. The energy will produce light snow over parts of the Great Basin, starting overnight Sunday, that will move into parts of the Central/Southern Rockies by Monday morning. On Monday, snow will develop over parts of the Central/Southern Plains, moving into the Middle Mississippi Valley overnight Monday and into parts of the Ohio Valley by Tuesday evening. The snow has prompted Winter Weather Advisories across parts of the Central Plains for Monday. Moreover, as the energy moves out of the Rockies, moisture from the Western Gulf of Mexico will stream northward over the Southern Plains on Monday afternoon producing showers and thunderstorms over parts of the Southern Plains, moving into the Lower Mississippi Valley overnight Monday. On Tuesday morning, rain will develop over parts of the Ohio Valley, expanding into parts of the Mid-Atlantic by Tuesday evening. In addition, showers and thunderstorms will begin to develop over parts of the Southeast on Tuesday afternoon. On Monday, a third area of upper-level energy will produce light snow over parts of the Upper Midwest. Furthermore, additional upper-level energy will move southward from West-Central Canada into the Northern High Plains on Monday afternoon. As a result, the energy produces light snow over parts of the Northern High/Northern Plains on Monday afternoon. On Monday, the light snow continues over parts of the Northern Plains/Upper Mississippi Valley that will expand into parts of the Great Lakes/Ohio Valley on Tuesday. The snow will result in reduced visibility and hazardous driving conditions.

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).
