Synopsis Cool fall weather will continue through the weekend with
gradually warming temperatures next week. Occasional north breezes
can be expected, especially down the colorado river valley.
Short term Through Tuesday. The upper level low pressure system
currently centered over southwest utah will begin to eject to the
northeast over the next two days leaving the area in a broad
troughing pattern through the week. Showers and an occasional
thunderstorms are developing across lincoln and northern mohave
county this afternoon and should last into the early evening time
period. Gusty winds out of the north will be a bit lighter
tomorrow and into Monday. Current forecast is on track and only
minor adjustments have been made.
Long term Tuesday night through Saturday.
The aforementioned troughing across the intermountain west will
linger over the region before the base of the trough closes off into
a cut off low by midweek with ridging building in from the pacific
nw. Medium range models are in relatively good agreement with the
general location of the cut off low, bringing it over az ut nv. By
Thursday, the southeasterly flow associated with the low will bring
enough moisture to allow for some isolated to scattered showers and
thunderstorms, mainly across NW arizona. The low begins to slowly
lift off to the NE Friday shifting the rain chances along with it,
and by Saturday ridging begins to take over.
These unseasonably cooler temperatures will slowly rebound to near
normal by the end of the work week. Through Wednesday, breezy north|
winds (especially along the colorado river valley) and mostly clear
skies can be expected each afternoon. By Thursday, the winds will
shift more easterly across northwest az and southern nv with mostly
clear to partly cloudy skies before diurnal winds and clear skies
Aviation For mccarran... Gusty northerly winds will remain
through the rest of the afternoon and evening, with speeds around
8 to 12 knots and gusts up around 20 knots. Direction through the
afternoon will favor north-northwest transitioning to a less
gusty northerly to northeasterly wind between 02z- 03z. A light
southwest drainage may set up later this evening but confidence in
timing is low, best approximation is between 05z-07z. Sunday will
feature a light northeast to east wind through the day and
a southwest drainage in the evening. Skies will improve this
evening to mostly clear conditions and remain so through Sunday.
For the rest of southern nevada, northwest arizona and southeast
california... Across lincoln county expect CIGS around 10-15k ft msl,
with showers and thunderstorms possible this afternoon and evening,
with associated mountain obscuration. For the rest of the region,
expect clear to scattered clouds with north to west winds 10 to 15
knots. Expect mostly clear skies areawide Sunday with similar winds.

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.
