Synopsis..Light northerly winds and fairly calm seas will remain through tomorrow evening. A round of showers are possible tomorrow night across offshore waters as a passing front pushes through. This front will lead to increasing winds and seas Wednesday night into Thursday. By Friday, winds and seas will be approaching cautionary, then advisory levels in offshore waters. Winds and seas will gradually settle down through the weekend. Mariners planning to boat on the eastern gulf later this week should Monitor the latest forecast for updates on these anticipated rough conditons.

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus62 ktbw 171737 afdtbw area forecast discussion national weather service tampa bay ruskin fl 137 pm edt Tue sep 17 2019 Short term An upper-level ridge that has been created in part by humberto and a tropical wave in the western gulf will be replaced by a positively tilted upper-level trough axis as it dives southward. This trough will serve to filter "cooler" and drier air into the area beginning late tomorrow night. For this afternoon evening, however, humberto continues to influence our weather as the cyclonic (clockwise) flow brings drier, continental air over the region. This is not unlike conditions for the rest of the week, but the more comfortable conditions are still trapped to the north of the peninsula. Complements of diurnal heating, lack of rain, and fewer clouds, temps are expected to reach the low-to-mid 90s for almost everywhere except the immediate coast between now and roughly 5pm. Unlike last week where high humidity combined with higher temperatures reached heat advisory criteria, the drier air should keep temperatures feeling closer to the actual value. It will still feel hot, but not as hot as last week. Thankfully, conditions will begin to transition tomorrow as the front makes it way through the area. A few showers are possible across the region, particularly tomorrow afternoon evening. Temperatures will respond to this change on Thursday with highs reaching the mid-to-upper 80s as opposed to the lower 90s. The humidity levels will be the most noticeable difference, with conditions feeling more comfortable beginning Thursday. Winds will also increase with a tighter pressure and thermal gradient across florida. Overall, Thursday will be a nice day across the region. Long term Conditions will gradually return to a late summer pattern through the weekend and into next week. A tropical wave passing through the florida straights will also facilitate the return of moisture to southern portions of the peninsula. There are noticeable discrepancies at this point in the forecast between the global models, with the precipitation parameterization schemes struggling to determine the northward exentent of the |
precipitation. However, there has been a northward trend in precipitation over the last couple cycles and this may continue. Overall, conditions are expected to warm up and humidity moisture levels will begin to return early next week. Aviation Vfr conditions are expected through the forecast period. Winds will become light and variable overnight and then light northeast on Wednesday. Marine Light northerly winds and fairly calm seas will remain through tomorrow evening. A round of showers are possible tomorrow night across offshore waters as a passing front pushes through. This front will lead to increasing winds and seas Wednesday night into Thursday.

Mariners planning to boat on the eastern gulf later this week should monitor the latest forecast for updates on these anticipated rough conditons. Fire weather Conditions will begin to dry out the remainder of this week. Aside from some low rain chances Wednesday afternoon evening, little-to-no rain is expected for the next several days. While drier comparatively to what has been the typical weather for the last few months, conditions are expected to remain above critical levels.

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. |
