short term... Tonight through Saturday night
not a lot of value added changes are forthcoming this afternoon
as all short term models are in generally good agreement. That
being said, a blend of forecast solutions will be used.

Mainly clear skies are in place across the area at this time as
high pressure is building over the area in the wake of Wednesdays
cold front. Temperatures at this hour ranged from the upper 50s
across the north to the lower 70s over the south. Winds are a bit
gusty at times but overall it was splendid first full day of
spring.

The aforementioned high will dominate on Friday with another dry
and generally sunny day expected. After a chilly start, temperatures
are expected to climb into the mid 60s to mid 70s across the
state. Meanwhile, the next storm system will be moving through the
four corners northern rockies on Friday before moving into the
central plains by early Saturday.

As the high slides to the east Saturday, return flow will get
reestablished and moisture will be on the increase. The central
plains system will move off to the northeast and drag a cold front
slowly across the region. Rain chances will increase accordingly
from west to east on Saturday and continue through the end of the
period. While widespread heavy rain is not expected, the slow
moving nature of this storm system will keep precipitation chances
in the forecast into the long term period. &&
long term... Sunday through Wednesday night
on Sunday, a compact surface and mid-level low is expected to
move across the northern plains. Some upper level energy
associated with this low should swing across ar providing periods
of enhanced ascent through midday Monday. Low level southwesterly
winds will increase through the morning allowing for moisture rich
air to stream into the region. Pw values should increase from
roughly 1 inch to around 1.5 inches by late Sunday evening. An
increasing moisture profile across the CWA and passing upper level
embedded impulses will combine with a weak frontal boundary to
help trigger showers and isolated thunderstorms through midday
Monday.

Despite return flow, dew points will struggle to reach 60
degrees across central portions of the state with lower values
found further north. Even across the south, only lower 60 dew
points are expected resulting in very low amounts of available
instability. Lapse rates are also not that impressive further
limiting instability potential, thus not expecting much in the way
of severe weather across the state. General rainfall amounts of 1
inch or less is expected through Monday however, isolated higher
amounts can not be ruled out.

The frontal boundary is expected to sweep across the state on
Monday, providing drier air and slightly cooler temperatures in its
wake. Upper level ridging and a surface high pressure will move
across the area through late Wednesday providing at least a couple
days of quiet weather across the region. By mid week, upper level
southwesterly flow returns as a new low develops over the rockies.

Rain chances begin to return to the forecast late Wednesday into
early Thursday, mainly across the northwestern half of the state.

Temperatures will be mild for the most of the long term, with highs
ranging from the 60s to mid 70s, and lows ranging from the 40s to
50s. However, Tuesday and Wednesday will be cooler with lows dipping
into the mid 30s across the north to mid 40s across the south. The
coolest day of the period should be on Wednesday with highs topping
out in the mid 50s to lower 60s. Thursday begins another warming
trend to round out the period.

Fire weather...

humidity is expected to drop into the upper 20th to the mid 30th
percentile Friday afternoon as high pressure moves over the area.

However, winds will be be light and overall dispersion is
expected to be generally poor. Moisture will begin to increase
over the area Saturday in advance of the next weather system. 10
hour fuels are expected to be around 10% for most of the state
with slightly higher moisture contents in the areas that saw
wetting rain on Wednesday.

Lzk watches warnings advisories None.

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.
