Farmers’ Almanac Extended Winter Forecast for 2023-2024

By MCS Staff

The Farmers’ Almanac has released its 2022-2023 extended winter outlook. MoCo and almost all of Maryland seem to fall under the “Frosty, Flakey, Slushy” category. Just to our south and west is the “Cold, Stormy” category, which means that we may have a good amount of winter precipitation for the first time in a few years, according to the forecast.

The Farmers’ Almanac suggests that those of us living along the I-95 corridor from Washington to Boston, who saw a lack of wintry precipitation last winter, should experience “quite the opposite, with lots of rain/sleet and snowstorms to contend with.”

Flood Watch in Effect; Severe Thunderstorms and Damaging Winds Possible Monday

By MCS Staff

A Flood Watch is in effect from 8PM this evening to 2AM Monday for half of MoCo and many parts of the DC region. Per the National Weather Service, “showers and thunderstorms are expected to move through the watch area with the potential to produce 1-2 inches of rainfall in a short time frame. Locally higher precipitation totals are possible.”

We are not in the clear after the flood warning expires at 2am Monday, as severe thunderstorms are likely Monday afternoon/evening with the threat of damaging winds, large hail, and a couple tornadoes, according to the National Weather Service. Earlier today, FOX 5’s Mike Thomas tweeted, “Monday’s bullseye is shifting and that’s not good. Remember that an outlook is simply looking at the atmosphere and saying “this is where something is *most likely* to happen”. It’s not a promise, but if realized, Monday does have dangerous potential.” We’ll keep an eye on how things progress for Monday. Featured photo courtesy of NOAA, photo below courtesy of the National Weather Service.
