12/28 – Rob Knight’s “FLASH FLOOD” Friday Morning Forecast
The main focus has been the HEAVY RAINFALL associated with a very slow moving cold front inching across the area. Many areas have seen in excess of 7 inches of rain with the area average for the locations that have seen activity overnight has been in the 3 to 5 inch range. With the line still producing bursts of heavy rainfall, the flash flood watch has been extended until noon. After midday, things should begin to improve across parts of the area and overall the rainfall rates should decrease.
The front is expected to stall over the area and will set up a classic over-running pattern with rain and t-storms developing back inland across the forecast area through the day on Saturday and Sunday. While rain chances will be elevated, there will likely be areas that experience substantially drier hours. Temperatures will be quite variable depending on what side of the front you are on and how strong the cold air advection is. Even with the front pushing toward the coast later this morning, it should remain mild with above normal temperatures today, but then trending cooler over the more inland areas on Saturday before recovering back to mild to warm highs again on Sunday. By early next week, another surface low will push a front through the area bringing another round of shower and thunderstorm activity. Temperatures will be much lower by mid-week with some lows in the 30s and 40s by Wednesday and Thursday mornings.
