May 24 Chase

8:15 PM Update: We moved slightly east mid-afternoon to the south of Aurora, NE to await the dryline that never came. The dryline ended up actually retreating to the west to the south of Grand Island or the I80 corridor and even north where the dryline was still moving east the storms struggled. Although several chasers/spotters reported a wall cloud or funnel, these reports came without warnings from the NWS so the validity of any rotation is suspect at this point. Maybe some more posts tonight once we look over some things from days past, and ahead for the next couple of days potential. Overall, today couldn't be as good as the past two and most chasers busted unless you were somehow lucky enough to be in northern Oklahoma.

-------------------------------------------------------------------------------------

3:45 PM Update: Still awaiting some good signs of convection, some small cells to our northwest that may be able to do something. At this time however, they don't look like much. Still working on issues with the mesonets, etc., will hopefully be ready to go shortly as tornado watch has already been issued for the area.

-------------------------------------------------------------------------------------

3:00 PM Update: Currently just to the south of Grand Island, awaiting the dryline to develop here in central/eastern Nebraska. Managing some minor repairs still, but doesn't look to be too much longer before we start to see something on the day. Definitely does not look to be as good as the past two, but hopes still good that we'll see something today! Overall the reasoning behind not as high tornado hopes includes the fact that overall shear is not as good, with more southerly flow at the surface to go along with southwesterly flow aloft. Instability (moisture) not as good either, but still sufficient.

-------------------------------------------------------------------------------------

12:00 PM Update: Currently on the roads of Kansas, just south of Nebraska and our target area for the day in southeast Nebraska. Today doesn't seem nearly as good as the previous two, but the entire group is still confident that tornadic supercells will not be lacking today. Today may actually turn out slightly better to the fact that we won't have continual development and a training of tornadic supercells. Or this could also be a bad thing as if we lose the one tornadic storm, then there is nothing else to fall back on. Either way, today looks to be another solid day of chasing for many who have taken off this holiday weekend to get their storm chasing 'vacation'. Currently the best forecast will have a cold front over SD/NE with a dryline as well over parts of southern NE/KS/OK/TX. Surface winds from the southeast should favor convergence along these fronts with winds to the southwest or west. Instability should not be lacking, even though dewpoints are not nearly as high as yesterday in Kansas. Should not be quite as exciting or early as yesterday's beginning, so I should have another update later this afternoon.
