| 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.
The main weather headlines are associated with the broad low pressure
system that is impacting the central and eastern U.S. this week. This low
pressure system is triggering severe weather from East Texas to the Great
Lakes and producing wintry conditions in the northern Plains and Maine
today. Hazardous weather conditions will likely continue through tonight.The Storm Prediction Center has issued a broad Slight Risk (level 2/5) of
Severe Thunderstorms from East Texas and northern Louisiana to the eastern
Great Lakes region with an embedded Enhanced Risk (level 3/5) area over
parts of the Ohio Rover Valley. A long line of eastward moving showers and
thunderstorms has developed across this area ahead of a cold front.
Potential storm hazards through tonight include damaging winds, large
hail, and a few tornadoes. Localized heavy rainfall may also produce
isolated to scattered instances of flash flooding, and there is a Slight
Risk (level 2/4) of Excessive Rainfall in effect from Texas to Kentucky
and east of Lake Ontario.Wintry weather is occurring today on the northern and western sides of the
low pressure system in the northern Plains and New England. Blizzard
warnings are in effect for parts of the Dakotas where snow showers and
strong winds will cause blowing snow and reduced visibility, which will
make travel dangerous. Additional snowfall totals from today may be
several inches across eastern North Dakota and northern Minnesota. To the
East, wintry mixed precipitation will fall mainly as sleet and freezing
rain across the Upper Great Lakes and New England. Winter Weather
Advisories are in effect for parts of Maine, New Hampshire, and Vermont
through early Thursday morning. Isolated power outages and slippery travel
are anticipated in these areas. Wintry precipitation will gradually taper
off overnight and early Thursday morning.Conditions will improve on Thursday as the low pressure system pushes
further north into Canada. The trailing cold front will approach the East
Coast and northern Gulf Coast on Thursday while slowing down and
weakening. The severe threat will decrease, and only isolated severe
thunderstorms will be possible in the Mid-Atlantic and parts of Texas
where the Storm Prediction Center has issued a Marginal Risk (level 1/5)
of Severe Thunderstorms. The front will stall near the Gulf coast, which
will prolong the risk of isolated to scattered flash flooding in the
vicinity of the western/northern Gulf Coast and parts of the South through
Friday.Precipitation will also impact the Pacific Northwest through the end of
this week as two different frontal systems approach the region. Rounds of
precipitation are forecast, falling as rain at low elevations and mixed
precipitation and snow at higher elevations.Temperatures are abnormal today across the nation. Well above average high
temperatures are being observed east of the Mississippi River (excluding
New England where precipitation is keeping temperatures cooler), and well
below average high temperatures are being observed west of the Mississippi
River (coldest in the Intermountain West and northern and central Plains).
Temperatures will return to near average values for this time of year as
we approach the end of the work week.
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.
