Saturday was the warmest day of 2021 so far with highs 72-77 over much of the area, though Rensselaer & Morocco were cooler at 67.
Early spring indeed, we have seen the greatest number of 70 or greater days in March since the record warm March of 2012. March 2021 is the warmest March so far since 2012.
This has been a very early start to the more April-May type severe weather outbreaks. The first two back to back High Risk periods occurred since April 1991.
In this most recent round, severe weather occurred from Texas to Virginia & Indiana & Ohio to Mississippi.
This was another big outbreak of severe weather with major flooding, especially in Tennessee. 9.50" of rainfall has occurred in the past 24 hours in the Nashville, Tennessee area with roads & railroads washed out.
1 person was killed in Hamilton County, Indiana when tree fell during storm. 1" hail was reported just southeast of the area. Reports from southern Montgomery County are of 0.25-0.75" diameter hail. 0.25" was reported just east of Logansport. 52 mph wind gust was measured at Grissom ARB. 50 mph gust occurred near New Market.
This follows the HIGH RISK day of just a few days ago. Multiple tornadoes exceeded 50 miles in path length.
EF4 in Georgia tracked more than 65 miles. EF3 near Birmingham, Alabama tracked more than 50 miles.
Tornado count continues to rise. At last check it was 19 with 5 deaths.
This followed 48 tornadoes confirmed in March 16-17 outbreak, though none of the tornadoes exceeded high-end EF2 strength (at least right now).
Gradient non-t'storm winds have been strong since early this morning with gusts up to 45 mph measured.
It is also a much colder day with temperatures currently in the 40s. A few spotty showers are possible in the northeastern half of the viewing area today.
Some clearing is possible later today-tonight with lows 30-34, followed by sun, strong south winds & 60-68 Monday.
Tuesday looks even warmer with 66-73 with south wind to 41 mph.
Rainfall is likely Tuesday night-early Wednesday morning.
Any storms & severe risk currently looks to stay well south of our area.tmph.
Wednesday looks much cooler with highs 45-50, followed by 45-50 Thursday. Lows of 25-30 are expected.
It will turn much warmer Friday with 57-64, then 67-74 Saturday & 70s Sunday.
Very warm weather dominates April 5-10 with highs in the 70s & 80s, followed by showers/storms around April 7-8 with even some severe weather risk developing.
April 7-10 shows a tendency for frequent bouts of showers & storms with severe weather risk. Best risk is with the passage of the main upper trough April 9-10.
There is not much cool weather at all April 3-15. It looks the warmest since 2010.
However, after showers/storms, April 16-25 (right now) continues to trend drier than with some cooler weather with frost at times. Trends point to the last light freeze/frost near April 22, but the overall above normal temperatures will push vegetation up to 2 weeks ahead of schedule.
A clipper or two may pass. Clippers can have very cold pockets aloft associated with them. I have seen clipper produce some severe weather before (often hail), so that is not completely out of the question in an overall drier regime.
Big warmth with 80s are expected April 27-May 1 with showers & storms returning. Severe weather risk develops, as well.
