(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus62 ktbw 240718 afdtbw area forecast discussion national weather service tampa bay ruskin fl 318 am edt Sat aug 24 2019 Discussion Across the southern fl peninsula a weak area of low pressure remains in place. Cyclonic flow around this feature will keep much of the area in an NE flow today. Similar to yesterday, drier air looks to suppress afternoon convection somewhat, especially north of i-4. Across far southern portions of the area, closer to the low, more moisture should be present which will allow for pops in the 40-60 range. On Sunday the low will begin to move further north with a light northerly flow over the region. Highest moisture will be present across the space coast so rain chances again for much of the area should remain scattered in nature... Highest inland. The low pressure area will begin to move away from the region Sunday night and into Monday. The departing system will create southwest flow on Monday and with ample moisture present expect morning showers thunderstorms gradually migrating inland throughout the day. Through mid week, west to northwest flow will be countered by broad cyclonic flow and ample moisture, allowing for rather sporadic rain chances each day. By Thursday into Friday, a tropical upper tropospheric trough (tutt) will be moving westward across cuba. While this upper level feature will be well to our south, some enhancement at the lower levels may induce a weak area of low pressure along a frontal boundary and bring an increase in pops as we end the work week. Otherwise, temperatures will be near average for this time of year but daily cloud cover and precipitation activity will dictate temperatures by a few degrees. |
Aviation Vfr conditions expected through the rest of the morning and into early afternoon. Scattered to numerous showers and thunderstorms are expected to develop during the afternoon, causing brief periods of MVFR ifr conditions as storms move over individual terminals. Marine A weak area of low pressure will linger over south florida this weekend, setting up light northerly winds over the coastal waters. As the low lifts north and high pressure ridges into the southern gulf of mexico, winds will shift to westerly and southwesterly during the first half of next week. Winds will generally remain less than 15 knots with seas of no more than 2 feet, although daily thunderstorms will create locally hazardous boating conditions. Fire weather Sufficient low level moisture will keep relative humidity values above critical levels through the week with no red flag conditions expected. No significant fog is expected through the period.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
