You think it cant get any colder, well the present bubble of cold air in down near Panama and there is another front coming down to support it and keep the cold air coming. . . . My guess is that by tomorrow it will be colder than yesterday, but today will be a little warmer than the last couple of days, if, and only if this present cloud thins and we get some sunshine.
Looks like today will be cloudier than yesterday and cool if the cloud does not thin, no rain expected.
