Cristobal Remnants June 9-10

Why not

June tropical systems that are in the vicinity of where Cristobal is located pretty much always make landfall in Louisiana or Texas, so based on that and current model guidance, a landfall somewhere in Louisiana or possibly far eastern Texas looks very likely. 

Beyond that, the big question for us is how the remnants interact/phase with an incoming trough from the west.  There are a range of possibilities here from just getting some remnant moisture to a more pronounced interaction that results in an unseasonably deep surface low with a severe weather and strong wind threat.  We shall see.

I am hoping for no phase or even better storm dying down there. If the low does occur it would put us into a cold pattern for at least a week afterwards, some models even longer. Only a solution like the 12z run yesterday would be fine with me, for record purposes.

yeah 12z Euro has below zero 850 temps as far south as northern Illinois by next Friday morning.  woof

How hard is it to get a remnant Gulf system to track northwest of Illinois?  Pretty hard

It is not unusual for the heaviest rains to shift along/west of track as these things move farther inland, so some of these may have been able to produce rain into parts of IA/WI, especially eastern areas.

Path of this thing for much of its time after landfall may take it over a zone that has been wetter than average.  Wonder if there may be somewhat of a brown ocean effect.  It's one of those things that is hard to measure.

Could be some of that, but the pattern is so amped up - adding tropical heat into a favorable synoptic pattern could definitely lead to rapid deepening. The trough coming into the West has near record low 500 mb heights for June in the PacNW:

I don't like the idea of those PWATS combined with a very strong low and tropical remnants. That could be a potentially serious flood threat, especially if it goes over the very wet areas from the last couple of weeks. Combined with the potential wind and this could be quite interesting next Wednesday/Thursday.

Good news is that it's flying northwards by the time it gets here, but that wouldn't preclude some 5"+ amounts in a 6-12 hour period. I'm growing more concerned for lakeshore flooding, even surge/seiche, and the resulting erosion too. Most of the 00Z guidance is showing 50-60KT+ wind potential.

00z Euro came in fairly impressive.

I think it's going to be at least a couple days until we get a better idea on the intricate details of the interaction with the incoming trough.  

Mentioned a few examples (in the other thread) of storms that were more memorable from a wind perspective.  They are outliers among tropical remnants in the region for a reason, but every so often you get your 1900, 1941, 2008 type storms that produce a swath of 60-80 mph winds as they move through.  If things come together right, then something like that scenario could be on the table, but we'll just have to wait and see.

70KT LLJ there over LM. Gets down to about 980 mb at the sfc.2109271127_ScreenShot2020-06-05at1_48_18AM.thumb.png.7d88d3607008702a0c4be119abfe81bf.png

The ICON sped up this morning.  A faster motion should help get the system a bit farther nw before the front swings through.

Does the ICON have a CAPE map available?  It looks like this evolution may give a shot at some thunderstorms, not sure of the severity, but timing may be decent to let us destabilize.

Does the fact that Cristobal has been stuck over the Yucatan for several days and will likely have to rebuild its tropical convective core from near-scratch as it comes back across the GOM have any bearing on impacts for us vs. some of the runs which showed it getting back over water quicker and becoming a Cat 1--2 hurricane?

If some of these runs are to be believed it could become quite a bit deeper over the Midwest than it ever does as a tropical system.
