KEEPING THURSDAY DRY……….
I think Thursday will stay dry & all rain will stay southeast………dew points are low……if there is anything, would likely be virga (evaporating rain before it hits ground due to low dew points) with clouds & sun…………WILL WATCH……..
STRONG STORM SYSTEM FRIDAY-FRIDAY NIGHT WITH TORNADO OUTBREAK………….READ FURTHER TO GET DETAILS ON THE EFFECT ON US……….
EASTERN UNITED STATES……………..
1. It appears as of right now……strong low pressure will track from southern Missouri to Terre Haute to Ft. Wayne late Friday-Friday night.
2. This system will likely bring a violent tornado outbreak to parts of the eastern U.S.
3. This outbreak may become a national news story. The current dynamical & instability parameters support 30-40 tornadoes over an 8-state area with many of them violent EF3’s & EF4’s.
4. Personally, I think the Storm Prediction Center will put out a HIGH RISK of severe & tornadoes over parts of the eastern U.S. for late Friday by tomorrow afternoon.
5. With this track, most of the severe storms & 75-80 temps will stay just south of the Valley.
6. The storm should arrive Friday evening & leave by Saturday morning with lingering effects Saturday afternoon in the form of wind & a scattering of chilly rain showers.
THE WABASH VALLEY………………
1. The current low pressure track supports the worst of the outbreak occurring in Kentucky, Tennessee, Mississippi, Alabama & eastern Arkansas.
2. Other tornadoes may occur in southern Ohio, Indiana, Virginia, South Carolina, North Carolina, West Virginia, even western Maryland.
3. However, this track also brings a slight tornado threat as far north as Olney, Robinson, Sullivan, Vincennes, Bloomington, Spencer & Washington to Bedford Friday night.
4. The storm track will mean EVERYTHING……………if it shifts 80 miles north & we get into that 75-80 degree warm sector we could get into the outbreak.
5. The current low track means 65-70 with severe threat in our southern counties with 80s & violent tornadoes just south of Indiana.
6. THIS NEEDS TO BE WATCHED VERY CLOSELY……………WITH SUCH A STRONG LOW, NOT ONLY WILL ACHES & PAINS BE COMMON FRIDAY-SATURDAY DUE TO LOWERING PRESSURE, BUT THE STRENGTH OF THIS LOW WILL BRING TORNADOES, IT IS JUST A MATTER OF WHERE EXACTLY THEY WILL OCCUR.
MUCH, MUCH COLDER OVER THE WEEKEND…………
1. Gray, gloomy skies with periodic showers & northwest winds to 40 mph will dominate Saturday after a high of 53 in the morning, then 45-50 in the afternoon.
2. Gray, gloomy skies with northwest winds up to 32 mph will dominate Sunday with clearing by evening. Highs will only be 38-43!
3. Clear skies Sunday night & calming winds will result in lows of 23-26, causing some damage to budding & blooming trees. FRUIT GROWERS BEWARE!!!
COOL START TO APRIL……………
1. 50s for highs & 30s for lows will dominate through April 5.
2. April 4 looks like a particularly cold night with lows of 25-30.
3. Largely dry weather will occur during this time.
BIG WARM-UP!!!!!!
1. 70s will return by the 7th & we could see 80 by the 8th!!!!
2. HUGE ridge of high pressure will arrive with 5,000’ temps to 18C, signaling very warm weather!!!!
3. This period through April 12 looks quite dry.
4. Farmers will be in a working/planting frenzy with the warmth & dryness.
