October 20, 2022: U.S. 48-Hour Weather Report and Intermediate-Term Outlooks; Tropical and World Precipitation

Here is what we are paying attention to this morning and the next 48 hours from this morning’s NWS Forecast.

...Above normal warmth in the Central U.S. through this weekend...

...Critical Fire Weather conditions for Montana and Wyoming...

...Increasing precipitation chances and decreasing temperatures in the
West this weekend...

Continuation of the NWS Short Range Forecast (It is updated twice a day and these updates can be found here.

After the cold snap earlier this week, temperatures have been warming back
up in the Central and Eastern U.S. Above normal temperatures are forecast
for the Central U.S. through this weekend. High temperatures could reach
as high as 20-25 degrees above normal into the upper 70s and lower 80s in
parts of the Midwest. The Eastern U.S. will also feel the warming trend
with highs gradually returning to near to slightly above normal by Sunday.
Chilly overnight low temperatures are expected tonight and Friday night
across the Southeast and east of the Appalachians; however, lows will not
be as cold as they have been the past couple nights. Frost Advisories will
be in effect tonight for portions of the Mid-Atlantic from Northern
Virginia to New Jersey.

Most of the continental U.S. has entered a brief period of dry weather
with little to no precipitation. Precipitation is expected to return on
Friday to the Pacific Northwest as a low pressure system begins to move
southeast across the region. Gusty winds and dry weather ahead of this
system will contribute to increased fire danger for portions of the
Plains, Great Basin, and Ohio River Valley. Fire Weather Watches and Red
Flag Warnings are in effect for portions of these regions. The Storm
Prediction Center has highlighted an area on Critical Fire Weather
conditions in Central and Eastern Montana today and Southern Wyoming
Friday where rapid fire spread will be possible. Those affected should
listen to local officials for fire safety information.

Precipitation chances will increase while temperatures decrease this
weekend across the Western U.S. as the low pressure system pushes a cold
front southeast. Precipitation chances will begin on Friday for the far
Pacific Northwest, then expand across the Northwest and northern Rockies
on Saturday, and push into the Intermountain West and Plains on Sunday.
Precipitation should help to decrease fire danger in some areas. Rain is
expected at low and mid elevations, and mixed precipitation is expected at
higher elevations. Heavy mountain snow will also be possible. Below normal
temperatures are expected in the western U.S. behind the cold front. High
temperatures will drop nearly 30 degrees from the 70s and 80s today to the
40s and 50s on Sunday.

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.

The following is provided to help the reader relate the maps and the discussion that comes with the maps to how NWS will describe an area of the U.S.
