Marine Weather and Tides
12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed.
10/9/2019 Updated the Marine Zones.
9/4/2019 Fixed the weather maps due to NOAA moving them.
7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports.

SHORT TERM. (Today through Sunday night) Issued at 430 AM MDT Sat Jul 11 2020
Synoptic Overview: WNW flow aloft will prevail over the region, on the NNE periphery of an amplifying upper level ridge over the Desert Southwest and Southern Plains.
Through Tonight: Weak/broad high pressure in the lee of the Northern Rockies (assoc/w subsidence in the wake of shortwave energy progressing eastward across the Northern Plains) will extend southward into the Central Plains as an effective cold front shortly after sunrise this morning, with winds shifting to the N and increasing to 20-30 mph in the wake of the fropa. Short- lived as it may be, this change in airmass should be sufficient to offset what would otherwise be additional warming (beneath the amplifying ridge) -- keeping highs in the lower-mid 90s. Dry conditions will persist, i.e. convection is not anticipated.
Sun-Sun night: A moist low-level southerly return flow will develop in Eastern CO/Western KS on Sunday as the mslp gradient tightens between a developing lee trough in Eastern CO and the weak/broad SFC-H85 ridge lingering over Central/Eastern KS. Differential heating and a relatively moist upslope flow along the southern flank of the Palmer Divide may aid in the development of isold convection around peak heating -- in an environment characterized by steep mid-level lapse rates (7.5-8.5 C/km), moderate instability (1500-2000 J/kg mlcape), strong DCAPE (1200-1700 J/kg), and ~40 knots effective deep-layer shear. Thus, a conditional potential for isolated supercells capable of producing large hail and damaging winds will exist late Sunday afternoon and evening, mainly in Eastern CO (350 deg @ 8-15 kt for right-movers).
LONG TERM. (Monday through Saturday) Issued at 314 AM MDT Sat Jul 11 2020
For the extended period the models are showing a pattern of an upper- level ridge over the High Plains between two troughs over the Idaho Panhandle and the Great Lakes region/Southeastern US. By Tuesday, the ridge will move out of the plains and into the Great lakes region while the trough moves in and replaces it over the northern Plains. At the same time an high height center builds over the Mexico/US broader. This will set up a zonal upper-level flow over the local area for the rest of the period.
On the surface, a cold front looks to move through the area at the beginning of the week and produce a slight chance of showers and thunderstorms on Monday. Followed by a series of mid-level troughs, coming off the Front Range, producing afternoon showers and thunderstorms Tuesday through Wednesday.
For the rest of the period, the NBM is showing mostly dry conditions as the area will be under the the influence of the upper- level high centered over Texas. However, it is possible that another shortwave could move off the Front Range and into the local area so isolated isolated showers/storms can not be ruled out.
As for temperatures, Monday will be in the upper 90s up until the front moves through. Behind the front the region will see highs reaching the upper 80s during the middle of the week before a warming trend brings highs back into the upper 90s by the end of next week and into next weekend.
AVIATION. (For the 12Z TAFS through 12Z Sunday morning) Issued at 500 AM MDT Sat Jul 11 2020
A brief period of MVFR ceilings cannot be ruled out at the MCK terminal shortly after sunrise this morning Otherwise. VFR conditions will prevail through the TAF period. Winds will abruptly shift to the NNW-N and increase to 15-25 kt gusting up to ~30 kt in the wake of an effective cold frontal passage this morning. Expect the breeziest conditions during the late morning, with winds veering slightly to the N-NNE and decreasing to 12-18 knots by mid-late afternoon. Winds will further veer to the NE-ENE and decrease to 5-10 knots tonight.

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.
