chilly temperatures for much of the eastern U.S….…Unsettled weather for the Pacific Northwest while the rest of the West
sees a warm up……Above average temperatures spread throughout the Plains and Midwest;
Critical Risk of Fire Weather Saturday in the Central Plains…
Information Note: This article is now set up so that all the maps should automatically update. The links are provided but should not be needed. The downside is that if you go back to a previous version the maps will have been updated and not be relevant to the date of the prior article but will be current information. The NWS twice-a-day 48-hour forecasts do not auto-update in this article. I do it and I can be late doing it. The link for the NWS updates is HERE. Most of our other articles will not be set up to auto-update so that prior versions of the article will be meaningful.
Last night we published the Updated Outlook for the month of April. You can access it HERE. Remember the easiest way to get back to the article you were reading is to hit the return arrow in the upper left of your screen. There are other ways. |
First, the 48-Hour Forecast (It is a 48 to 72 Hour Forecast actually)
Daily weather maps. I try to keep the below three maps updated. The Day 1 map updates twice a day and the Day 2 and 3 maps update only once a day. I will be doing the updating during the period described in the title of the article but if you happen to read this article later, you can get updates by clicking HERE
TODAY (or late in the day the evening/overnight map will appear)
TOMORROW
NEXT DAY

ATMOSPHERIC RIVERS
This tells us what is approaching the West Coast. Click HERE to update If I have not gotten around to doing the update. Here is some useful information about Atmospheric Rivers.
Continuation of the NWS Short Range Forecast. It is updated by NWS twice a day and these updates can be found here. We post at least one of those updates daily, sometimes both. The Highlights are shown in the lede paragraph of this article.
A frontal boundary lingering across portions of the Southeast and Gulf
Coast will continue to bring showers and thunderstorms to the region on
Saturday. Some moderate to locally heavy rainfall will be possible,
particularly from the Florida Panhandle/southeastern Alabama into central
Georgia, South Carolina, and eastern North Carolina where there is a
Marginal Risk of Excessive Rainfall (level 1/4). Conditions will finally
begin to clear out for most areas by Saturday night, while showers and
thunderstorms will linger across the Florida Peninsula on Sunday. Chilly
air will remain in place for most of the East Coast this weekend following
the passage of this frontal boundary. Temperatures will be particularly
cool for portions of the Southeast into the Carolinas where highs in the
40s and 50s are 20 to 25 degrees below average for early April. In fact,
some of these highs will be close to record-tying/breaking low maximum
temperatures for the date on Saturday. Elsewhere, highs on Saturday will
be in the 30s and 40s for New England and other interior portions of the
Northeast and the 50s for the Mid-Atlantic. Temperatures will warm up by
about 5-10 degrees for Sunday. The Southern Plains and Lower Mississippi
Valley will also be seeing below average temperatures, with highs
generally in the 60s and low 70s, even as far south as south Texas.
Florida will remain the one warm spot on Saturday with highs in the
mid-80s, although temperatures will cool here as well for the northern
Peninsula as the sagging front ushers in highs in the 60s Sunday.A system currently moving through the Northwest will continue to bring
some light to moderate lower elevation/valley rain and higher elevation
mountain snow to the Pacific Northwest, northern Rockies, northern
California, and the northern Great Basin Friday evening and lingering into
Saturday morning. Conditions will clear out for most of the region by
Saturday evening while a series of additional Pacific systems continues to
keep moisture flowing into the Pacific Northwest. Some moderate to heavy
higher elevation snow is forecast for the Olympic mountains and northern
Cascades while lower elevation/coastal locations will see moderate to
locally heavy rain, especially along the coast. Meanwhile, the rest of the
West will see a mostly welcome pattern change after what has been quite
the cold winter and early Spring so far. Upper-level ridging will build in
over the weekend ushering in drier and warmer conditions Saturday into
Sunday outside of the Pacific Northwest. Highs Saturday will generally be
in the 50s and 60s across the Pacific Northwest, northern California,
Great Basin, and the Rockies, with temperatures reaching into the upper
70s to mid-80s for the Desert Southwest. Temperatures start to soar well
above average on Sunday with highs into the low 70s as far north as the
northern Great Basin. More generally, highs will be in 60s and 70s for
California, the Great Basin, and the Rockies, with upper 80s to low 90s in
the Desert Southwest. The one caveat to the warmer temperatures will be an
increasing risk of rising rivers, streams, and minor flooding in other
low-lying areas as these warmer temperatures will cause some of the
significant snowpack over the region to melt. The Pacific Northwest will
remain cooler as the weather stays unsettled in the region, with highs in
the 50s.Most of the Central/Northern Plains and Midwest will also see a warm up
Saturday into Sunday, with highs in 60s and 70s from the Central High
Plains east to the Upper Mississippi Valley Saturday spreading into the
Northern High Plains and much of the Great Lakes region Sunday. These
warmer temperatures along with very dry conditions and gustier winds have
prompted a Critical Risk of Fire Weather Saturday from the Storm
Prediction Center for portions of the Central Plains. Temperatures will
remain chilly where there is still some snow cover from the recent winter
storm over the eastern Dakotas, with highs in the 30s and 40s. An upper
level shortwave moving across the Plains on Sunday will bring the chance
for some scattered showers and thunderstorms to portions of the
Central/Southern Plains Sunday evening.
Below is the current five-day cumulative forecast of precipitation (Updates can be found HERE)
Now we look at Intermediate-Term “Outlook” maps 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 as deviation from normal and the likelihood of these deviations.
Below are the links to obtain updates and additional information. They are particularly useful if you happen to be reading this article significantly later than when it was published. I always try to provide readers with the source of the information in my articles.
Days 6 – 10 (shown in Row 1) | Days 8 – 14 (Shown in Row 2) | Weeks 3 and 4 (Shown in Row 3 but updates only on Fridays) |

Showing the actual maps. They should now update automatically. The Week 3 – 4 Outlook only updates on Fridays. So below is what I call the Intermediate-term outlook. On Fridays, it extends out 28 Days. That declines day by day so on Thursday it only looks out 22 days until the next day when the Week 3 – 4 Outlook is updated and this extends the outlook by one additional week.

HAZARDS OUTLOOKS
Click here for the latest complete Day 3 -7 Hazards forecast which updates only on weekdays. Once a week probably Monday or Tuesday I will update the images. I provided the link for readers to get daily updates on weekdays. Use your own judgment to decide if you need to update these images. I update almost all the images Friday Night for the weekend edition of this Weather Report. So normally readers do not need to update these images but if the weather is changing quickly you may want to.
