2018 Teddy Bear Fund Raiser Campaign!

We are about $500 short for our fundraiser.  Please consider donating $5 or $10.  Much appreciated!

The Shadow Angel Foundation is raising money for new teddy bears to be donated to Child Watch and PASAC of western Kentucky. This is our 15th year of donating new bears to these two organizations.

This is a matching fundraiser. That means your donation is doubled.

The KPAH WSR-88D Doppler radar operated by the NOAA National Weather Service in Paducah,
KY will be down for a little over three weeks for the repair of a major mechanical component.

An engineering team from the Radar Operations Center (ROC) in Norman, Oklahoma, determined
that the bull gear, the primary gear for turning the radar antenna, has failed. This repair will
require 12,000 to 15,000 pounds of equipment and a six-person team from the ROC to restore
the radar. At this time, the team anticipates repairs being completed during the next couple of
weeks with the radar returning to service by May 11th.

During the downtime, adjacent NWS supporting radars include:
Springfield, MO (KSGF)
St. Louis, MO (KLSX)
Lincoln, IL (KILX)
Indianapolis, IN (KIND)
Louisville, KY (KLVX)
Evansville, IN (KVWX)
Fort Campbell, KY (KHPX)
Nashville, TN (KOHX)
Memphis, TN (KNQA)
Little Rock, AR (KLZK).

The Paducah, KY WSR-88D is 23 years old and part of a network of 159 operational radars. The
radars are supported by three federal agencies: NOAA National Weather Service, United States
Air Force, and the Federal Aviation Administration. The Radar Operations Center provides
lifecycle management and support for all WSR-88Ds.

Example of a recent severe weather alert.  I issued this well before the official tornado warning.  You would have had plenty of time for you and your family to seek shelter.

Your $3 per month also helps support these local charity projects.

I encourage subscribers to use the app vs regular text messaging.  We have found text messaging to be delayed during severe weather.  The app typically will receive the messages instantly.  I recommend people have three to four methods of receiving their severe weather information.

Remember, my app and text alerts are hand typed and not computer generated.  You are being given personal attention during significant weather events.

THE UPDATE BELOW IS FROM EARLIER TODAY.

I HAVE SINCE ADDED INCREASED RAIN CHANCES WEDNESDAY INTO WEDNESDAY NIGHT ACROSS PORTIONS OF THE REGION

 

RAIN TOTALS

This is the 24-hour rainfall forecast.  If a thunderstorm forms then heavier totals will occur.

This is the NAM and GFS model.  It won’t be exact.  Take a general idea from the graphic.  Some bands of rain possible today as the upper-level low continues to pull away.

NAM

 

and GFS

 

 

Seven-day rainfall forecast

This will likely need some adjusting.  These totals depend on two systems.  One on Wednesday and one on Friday.

Models are not showing much rain in southern Illinois.  This will need to be monitored.

The greatest rain coverage (after today) will likely be Friday.  A band of showers and perhaps a thunderstorm along a passing cold front will push northwest to southeast through the region.

The National Weather Service defines a severe thunderstorm as one that produces quarter size hail or larger, 58 mph winds or greater, and/or a  tornado.

 

Tuesday through Sunday: Severe weather is not anticipated.  I can’t rule out lightning on Friday.

Weather Headlines

  • A few remaining showers today.
  • Mild temperatures into the weekend.
  • Isolated showers possible Wednesday afternoon into Thursday morning.  Most will remain dry.
  • A cold front on Friday with some additional rain chances.
  • Dry Saturday and Sunday.

 

Monday afternoon and evening delivered copious amounts of rain to some of our counties.  Rainfall totals range from 0.00″ to over two inches in a few locations.  Combine that with the rain totals from Sunday into Monday morning and some locations topped five inches of rain!

Many areas received one to two inches of rain through the event (Sunday night into Monday evening).

Numerous roads in western Kentucky experienced flooding.  Some roadways were even closed.

There were several reports of pea to dime size hail and at least one cold air funnel!

Many of you posted photographs of the cold air funnel.

What is a cold air funnel?

I grabbed this from one of my college professors.  From Haby Hints.

A cold air funnel is a high based weak circulation that occurs in a cool air mass. By high based it is meant it develops well above the earth’s surface. Since it is high based and weak they rarely impact the earth’s surface although they can look threatening. Unlike typical tornadoes, cold air funnels develop in a shallow cool air mass and often behind a cold frontal passage. The mixing of cool and windy conditions in the lower troposphere with air in the middle troposphere flowing in a different direction may spark the rotation that spins up the funnel. If the air is moist enough and rises enough the condensation funnel will be visible. The image below gives an idea of what these cold air funnels look like.

This photo was taken on the north side of Princeton, Kentucky, near Fredonia, Kentucky, Monday evening. Photo credit goes to Sara Choate.

 

 

Cold air funnels are usually associated with upper-level lows.  They rarely touch down and are normally just a novelty.  This one was well photographed.  I received 8 photographs of it.  There were also some videos posted online.

The funnel soon lifted after making a brief photographic appearance.

Conditions today will be a bit calmer.  Expect highs in the 60’s.  Not too bad for this time of the year.  A little below normal but we won’t complain.

We will still have a few remaining showers.  Perhaps an isolated thunderstorm.  The storm system responsible for our recent heavy rain will continue to pull off to the east and southeast.  The further east it travels the less rain coverage we will have.

There is a 20% to 40% chance of showers today.  Perhaps as high as 40% for our eastern counties.  Expect a few showers on radar but many areas will remain dry.

Here is the Hrrr model guidance future-cast radar.  What radar might look like today.  A few spotty showers.  This won’t be exact, of course.  One model’s opinion.

Timestamp upper left.

 

 

Temperatures today through Saturday will mostly be in the 60’s.  I can’t rule out 70 degrees by Sunday and Monday.  That sure will feel nice.

We will have to deal with some clouds over the next 36 hours.

Rain chances Tuesday night into Wednesday night will fall at or below 20%.  Plan on dry conditions.

A fast moving system will brush our region late Wednesday night and Thursday.  Perhaps isolated showers over southeast Missouri.  Low confidence on that happening.

Our next storm system will be a cold front that will pass through the region Friday.  I am still monitoring the timing of the system.  For now, it appears the front will pass through the region during the day.

Severe weather is unlikely.  I can’t rule out a thunderstorm.

It appears that a band of rain will accompany the cold front.  Rainfall totals will likely be at or below 0.50″.  Monitor updates since this is still several days away.

There remains some question about how much moisture the system will have to work with.  If we are lucky it will remain mostly dry.

The great news is that both Saturday and Sunday should be dry.  Finally, a dry weekend.  Let’s hope the forecast holds.  I know many of you have outdoor activities.

Here is the GFS future-cast radar.  This is the Friday system.  It shows light rain in our region.  It has a broken line of showers.  This is still a question.  Will it be a solid line of rain or broken line.
