November 6, 2022: U.S. 48-Hour Weather Report and Intermediate-Term Outlooks; Tropical and World Precipitation

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

...Moderate to Heavy coastal rain and mountain snow expected across the
West...

...Above normal temperatures continue in the East today, cooler air
expands across the West...

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


Calm weather is expected in the eastern U.S. through the short term
period. The lingering cold front along the East Coast is expected to
finally push offshore of the Northeast today while the tail lingers over
the Southeast and South. The frontal boundary has significantly weakened
with little to no impacts expected other than a chance of showers and
thunderstorms in the South. A strong high pressure ridge will build over
the eastern U.S. today and Tuesday, which will cause the remaining portion
of the boundary to dissipate.

In contrast to the calm in the East, unsettled weather will continue
across the West. A low pressure system will slowly slide down the coast,
continually pushing moisture over the region. Moderate to heavy rainfall
is expected over coastal and low elevation areas and moderate to heavy
mountain snow is expected over mid and high elevation areas. Anomalous
moisture will result in efficient rain rates that could lead to isolated
flash flooding in some areas. There is a Slight Risk of Excessive Rainfall
(level 2/4) in effect for portions of southwestern California on Tuesday
where flash flooding may occur, especially near steep terrain. While low
pressure remains along the coast a series of cold fronts will move across
the western U.S. and cause widespread winter weather at mid and high
elevations. Heavy mountain snow is expected at higher elevations in the
western mountains each day. A strong cold front will push out of the west
into the northern and central Plains Tuesday into Wednesday, spreading
winter weather into the Plains. Ahead of this front, breezy and dry
conditions will result in Elevated fire weather conditions for portions of
the Dakotas and Nebraska today.

Temperatures will drop in the West behind the cold fronts, and below
normal temperatures are expected to continue through the week. High
temperatures are forecast to reach 15-25 degrees below normal in some
areas with the highest departures from normal expected in portions of
Montana. Southerly flow across the Central U.S. ahead of the emerging
frontal system will result in above normal temperatures for much of the
region on Wednesday, but the region will cool post frontal passage later
this week. Above normal temperatures are also expected to continue in the
East today with highs in the upper 60s to lower 80s. Temperatures in the
East will return to seasonable values Tuesday and Wednesday.

Near the end of the short term period a tropical system is expected to
approach the CONUS from the southeast, which could impact to the portions
of the Southeast later this week.

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.
