9/23 – Brittany’s “Cooler” Friday Evening Forecast
Upper ridging over Texas will be in the process of getting suppressed southward by Saturday night and Sunday as a strong trough digs through the Great Lakes. This will eventually push a stronger cold front through the area, probably on Monday. Don`t really have deep moisture available, but there does appear to be sufficient instability to produce isolated to scattered convection Sunday afternoon. At this time, it appears that the front will be far enough south to keep any thunderstorm development Monday afternoon offshore. Beyond Monday, moisture levels will be insufficient to allow the development of any significant precipitation through the end of the forecast period.
Confidence has increased this morning that the eastern US trough and Monday`s cold front will keep newly formed Tropical Depression Nine (TD 9) currently in the Caribbean Sea to the east of our area. There is still enough uncertainty in the track forecast, however, that keeping up with the latest information on this system is still appropriate, as the system won`t exit the Caribbean until Monday night or Tuesday.
