I'm in Canton, TX and the NWS forecast discussion has injected some hope for seeing totality (~1:41-1:45 CDT):
Eclipse Details:
Despite being just ~12 hours from eclipse time, the cloud picture is really no more/less clear than it has been for the pasts everal days. One can find a model solution even in the very near term that supports any sky cover forecast desired, ranging from completely clear to overcast. However, the following currently seems to be the most likely scenario based on close scrutiny of model cloud cover and their typical performance/biases.
An intrusion of low stratus will spread northward into Central Texas by mid-morning, perhaps accompanied by patchy fog. Conditions will likely be at their worst between roughly 9 AM and noon, and the picture may look rather bleak for many during this time period as the low deck impinges on the DFW Metroplex and points to the north and northeast. However, most guidance is becoming increasingly bullish on fairly rapid scattering of this low cloud layer between 11 AM and 2 PM, and this would allow for decent viewing for many areas. That being said, some unlucky spots likely will remain socked in with low cloud cover, particularly across Central Texas, where any very low stratus and/or fog mixesi nto a broken or overcast layer by early afternoon. Guidance is slightly more optimistic in North Texas, with much guidance depicting scattering and even localized dissipation of the low deck prior to eclipse time. While some last vestiges of low stratus may be present, at least some partial viewability does seem likely for many areas of North Texas based on this trend.
Also by early afternoon, a plume of cirrus ahead of the previously discussed upper trough will be spreading in from the west, and these clouds are already present across far West Texas as of 1 AM. However, most guidance indicates that the main swath of the most dense cirrus will remain displaced mainly north of the CWA, with perhaps thinner and more scant cirrus across North Texas. As long as this cirrus does remain on the thinner side, many eclipse features would still be viewable through the veil. The low cloud evolution will be the main factor to watch over the next 12 hours, as a slower erosion of the low deck could still result in substantially worse viewing conditions due to its opaque nature.
