Here is what we are paying attention to in the next 48 to 72 hours. The article also includes weather maps for longer-term outlooks and a five-day World weather forecast.
We start with the U.S. Information.

| 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.
Recently, we published the Weather Update for June. You can access it HERE. We also published the Weekly Crop Report. It can be accessed 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. The Day 1 map updates twice a day and the Day 2 and 3 maps update only once a day. These maps update automatically. But if that does not happen, 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 rather strung-out omega block pattern will feature an upper low moving into Southern California with another just offshore New England while an upper high meanders over southern central Canada into the northern Plains. This orientation will act to maintain cooler than normal temperatures over much of the Southwest and Northeast for the next couple of days while much warmer than normal temperatures are favored over the Pacific Northwest into the Plains. The northeasterly flow out of southeastern Canada will be responsible for bringing in smoky/hazy and poor air quality conditions to parts of the Northeast and Great Lakes this afternoon/evening. Across parts of the southern High Plains (especially New Mexico into the Texas Panhandle), adequate moisture and afternoon instability may yield locally heavy rain where it has been quite wet recently, which could cause some flooding concerns. WPC has outlined a Slight Risk of excessive rainfall for this region through Wednesday, which includes some burn scar areas. More isolated to scattered shower and storms are forecast for portions of the Rockies and into the Sierra as well. The stalled system off New England will bring in bouts of rainfall to parts of the Northeast over the next couple of days as it spins just offshore. A frontal boundary on its southwest side will be reinforced from the north as cooler air wraps all the way around the system, bringing in drier than normal air as well to areas of the Mid-Atlantic and into the Southeast with dew points into the 40s (OH River Valley) to mid 60s (Southeast away from the coast). Over the Upper Midwest/Corn Belt, scattered showers and some thunderstorms are possible through Wednesday as well.

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.
