Desperately Needed Rain Falls

Image
There was hail up to 2" in diameter in north central Kansas. Elsewhere, the hail was smaller and scattered and should not have done a great deal of damage. 

Undulatus Clouds Over Southwest Kansas City Area

Image
Photos by Kathleen Smith Undulatus clouds, which are a cloud type like cumulus or cirrus, appeared over the southwest part of the Kansas City Metro this afternoon. When they occur, they are spectacular. In this case, they were on the leading edge of a cluster of thunderstorms.  So far, those thunderstorms have brought limited moisture (mix of rain, sleet, freezing rain). More in needed but these are the amounts to 4pm. 

Winter Wheat Rainfall Since June 1

Image
I thought it might be helpful to bring the June 1 to 6 rainfall across the winter wheat belt to your attention. In this area, most of the wheat is grown near and west of I-35. Currently, most analysts says that worldwide wheat supplies are "tight." This means that a good crop is especially needed this year.  I am concerned about flooding in areas where the wheat is ripe or ripening (generally south of the KS-OK border) causing the wheat to lessen in quality.  Regardless, drought conditions improved significantly during May. The latest drought conditions, as of Tuesday, are below.  Looking ahead, here is the forecast rainfall for the next seven days. 

48-Hour Rainfall Ending at 10pm Tuesday

Image
From east Wichita to northeast of El Dorado, 5 to 7 inches fell in a matter of hours. Data from the University of Oklahoma indicates this was roughly a once in 75 year event as serious flooding resulted, the worst I've seen.  The entire State of Kansas received rain -- in most places it was needed. However, the heavy rain may have interfered with the ripening wheat crop in places. 

Two-Week Great Plains Rainfall

Image
This is the rainfall across the Farm Belt during the past two weeks. I apologize for the white state borders but I cannot find a way to adjust the NWS's product. Below is the forecast rainfall to 7pm Monday the 28th. Additional rains will be welcome if they fall slowly enough as much of the area west of the Mississippi is still experiencing mild drought. 

This Week's Precipitation; Plus Storm Season Advice

Image
A very active week of weather is ahead! The gray square in the middle Mississippi Valley is an area where I believe the amount of precipitation is under-forecasted. This includes the areas from the Kansas Flint Hills to the Great Lakes where no rain is forecast to fall. There may also be snow, in significant mounts, farther south in Iowa and eastern Nebraska.  California, Oregon and Washington will continue to receive significant rain and snow (higher elevations) this week.  Tornado and Severe Thunderstorm Season Preparations   While preliminary, there is a good chance of severe thunderstorms near and east of Interstate 49 (roughly Kansas City to New Orleans) Friday and Saturday. If you have not prepared for tornado season 2025, the next few days will be a good opportunity to do so. What does that mean? Make sure family members know where to shelter in case a tornado warning if you aren't home.  Insure you have at least  two independent ways of receiving warning...

November Precipitation Summary

Image
Above is the November precipitation from the 1st to yesterday morning. Heavy rain fell in parts of the San Francisco Bay Area not fully accounted for on the national map. See below. Below is the forecast precipitation until 7am CST on the 30th. The West is off to a good start for rain and snow. 

Torrential Rain to Cause Flooding From California to Washington

Image
Extreme rainfall forecast for Northern California and the southwest corner of Oregon the rest of the week and into early next week. High winds accompanying the storm may cause power outages . Here is a detailed map where flooding is most likely. On some of the higher peaks, as much as 20 inches of rain is forecast to occur.  In San Francisco, amounts will be substantial, generally in the 3 to 4 inches range. However, Mount Tam may have more than seven inches by early next week.  Seattle may have 4 inches or more. And, for the first time this season, Los Angeles will be affected by an atmospheric river but the amounts will only be around a quarter inch with as much as a half-inch in the higher elevations.  This forecast could be more definitive if the Hurricane Hunter aircraft were available to survey the developing atmospheric river over the eastern Pacific. But, even though zero  hurricanes are forecast to occur the rest of hurricane season! See below: NCEP = NWS's ...

Rainfall: Fallen and Forecast

Image
Above is the 48 hour rainfall ending at 9am this morning. While helpful, in most winter wheat areas, far more rain is needed.  Below is the 7-day forecast of additional rainfall.  That is 7 inches of rain forecast in northeast and south central Oklahoma. 

Generous Rain Falls in the Winter Wheat Belt

Image
Above is a map of the desperately needed rain that has fallen during the 72 hours ending tag 1pm CDT. If you click on the title, you'll see the color scale.  More rain is forecast to fall. Below is a map showing the forecast rain from now until 6am CDT Monday.  This particular model is quite good as to location but the forecast amounts may be a bit heavy in places.  Below is a map of the winter wheat belt. As you can see, this rain fell in a critical area.  The map below is the drought situation before the rain fell. Unfortunately, the rain missed the extreme drought area near the Texas Big Bend.

Drought and Rainfall Update

Image
Here is the drought data as of Tuesday.  Fortunately, the areas of extreme or worse drought seems to be a little less bad than is often the case at this point in the summer. The drought map is compiled on Tuesdays. Below is a map of rainfall since that time.  Below is the rainfall amount forecast for the next five days...

11:10pm Wednesday: Tornado Watch Updated + HIGH Flash Flood Risk Thursday!

Image
Reminder: You can always get updates from me  on Twitter/X   @usweatherexpert. ------------- Tornado Watch in Effect Until 8am Thursday   Dangerous "High Risk" of Flash Flooding Thursday and Thursday Night   The vast majority  of flash flood deaths occur in "high risk" areas, even though only about 4% of days have high risk forecasts.  Of the flash flood deaths, the major involve people who are safe and then drive or walk into a flooded area. Remember: Turn Around, Don't Drown!! -- original posting still valid -- Heavy rain from the remains of Debby continue and are forecast for the next seven days. Flooding Forecast The major flood risk will continue in the Southeast with a serious flood risk developing from Pennsylvania to New England.  Tornado Risk There is a low risk of tornadoes in North Carolina the rest of today. However, there is a significant  risk of tornadoes on Thursday in the brown area. 

Debby Rainfall and Flooding Update

As of 10:50am, here is the situation. Rainfall to 10am Here are the storm total rainfall amounts to 10am for the Southeast.  Below is a closeup of the three areas of heaviest rainfalls. Additional Forecast Rainfall Some spots may receive up to a foot of rain, in addition to what has already fallen. Flooding Impacts Remember, the dots mean the flood forecast for rivers at a given location: Purple = record or major flooding Red = moderate Orange = mild flooding 

Summer Rainfall

#1 is the wettest since 1893. Conditions have been highly variable this summer. 

5:30pm Hurricane Warning for Texas Coast

Image
The red is a Hurricane Warning for part of the Texas Coast at this time.  H = Hurricane;  S = Tropical Storm;  D = Tropical Depression Maximum wind speed at landfall should be about 90 mph.  Here's the 10am Update from the National Hurricane Center. Other than a tropical storm warning for the south Texas coast, the forecast is unchanged. The storm surge forecast is below.  8:30am. Currently Beryl is a tropical storm with winds of 55-60 mph. However, it is forecast to reintensify as it moves toward the Texas coast.  Hurricane Beryl is forecast to have 90-95 mph sustained winds as it crosses the coast. The hurricane watch (pink) has been extended to just west of Galveston. The National Hurricane Center's (NHC) path looks good to me. The amber tint is where tropical storm force winds (40-74 mph) are in progress.  NHC has issued is a storm surge watch for the Texas coast from Brownsville to Galveston, including Galveston Bay and the Houston Ship Channel.
