Quick Update On This Storm, More Tomorrow On the Next One

24 Mar 2009, 8:20 am
HAMrad II Ptype With Fronts Valid 8am EDT
Our storm has held up quite well with our forecasts over the last 8 days and is still chugging along oriented over central South Dakota this morning. We still have a cornucopia of blizzard warnings and associated winter storm watches and warnings active for the region today. As we stated in yesterday’s discussion the low will lessen in intensity throughout the day before heading into Canada tomorrow afternoon.

As of the time of this writing there were 11 tornado reports received by the SPC with 8 reports of injuries associated with yesterday’s activity. In Cass County, Nebraska 5 injuries were reported as an outbuilding blew into a car, and three injuries where a tree fell onto a truck. Another fascinating report was from Staplehurst, Nebraska where 4.25″ hail was reported yesterday which is defined as larger than grapefruit sized hail, but just shy of the 4.5″ necessary to be classified as softball sized hail. While quite large, it does not quite reach the 7″ diameter stone from Aurora, Nebraska that fell in June 2003. Something certainly worthy of mention in the national media, but coverage has been very limited from this storm.

The SPC has issued a slight risk in their Convective Outlook category for today, and subsequent days as well that concentrate mostly in the southern states.

For today however, the risk area covers a wide swath from Illinois, through Missouri, Arkansas, eastern Texas, and northern Louisiana.

Today’s concerns revolve primarily around a shortwave that will accelerate through the bottom of the trough over the plains this evening and evolve into the region defined by the risk area. The shortwave and a strong associated low level jet will translate into a very favorable shear environment later this afternoon and this evening. However precipitable water becomes another issue for today, otherwise with the well rounded hodographs defined by the very favorable shear environment, today would have been a moderate risk day.

The SPC calls for wind to be the primary threat but does not rule out the possibility of tornadoes this afternoon as the trough moves through the region.

Day 1 Convective Outlook
SPC Day One Convective Outlook Valid 5am EDT
