3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues. 6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported. 5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive. |

Only exception will be kapf where afternoon sea breezes will again bring westerly flow along the gulf coast. Prev discussion issued 748 pm edt Fri apr 20 2018 update... mostly clear skies are still prevalent across south florida with the sea breeze advancements diminishing. Expecting light easterly flow to become dominant overnight as the surface high pressure axis slides eastward into the western atlantic. The SREF wasn't too excited about fog development tonight, so opted to keep mention out of the latest grid package. Other than loading in the latest wind and cloud cover guidance, all other variables appeared on track. Prev discussion... Issued 416 pm edt Fri apr 20 2018 discussion... weak high pressure over the peninsula has allowed for another warm and dry day across south florida. In response to light southerly flow across the region, a thermal surface low pressure center has developed in the interior, allowing both sea breezes to push well inland from their respective coasts. Latest wpc analysis depicts a cold front stalled east to west across central florida, north of lake okeechobee. As the front becomes nearly stationary tonight, it should act to increase easterly flow, especially noticeable over the atlantic and adjacent east coast metro. Expecting moisture to deepen in the lower levels with GFS forecast pwat increasing from around an inch to above 1.33". Weak lift generated from the stationary front, combined with this bump up in moisture should aid in the development of showers over the atlantic waters, then advect inland as Saturday progresses. Instability parameters appear rather weak on Saturday, though a rumble of thunder can not be ruled out in northern portions of our cwa. Late this weekend through mid next week: Saturday night into Sunday, mid range models continue to prog a potent low pressure system to slide eastward along the southern conus. Moisture ahead of the associated cold front will deepen further, as low level winds veer more south southeasterly. As confluence overspreads south florida and various vorticity maxima pass over the area, |
the atmosphere may begin to turn more unstable. Sunday afternoon, showers remain likely, with a chance of thunderstorms, esepcailly over the interior, with focus shifting to the northeastern portion of the peninsula as evening approaches. On Monday, flow continues to veer southerly or even south southwesterly. Expect repeat of Sundays activity with showers likely and a chance of thunderstorms. As forecast pwats increase to near 1.75", periods of moderate to occasionally heavy rain remain possible along central and northern portions of the east coast metro region. Both the ECMWF and GFS prog the aforementioned front to push through south florida sometime late Tuesday into Wednesday. In the wake of the front, dry conditions are forecast prevail mid to late next week.
