It is difficult to find a more comprehensive Weather Outlook anywhere else with the ability to get a local 10-day Forecast also.

This article focuses on what we are paying attention to in the next 48 to 72 hours. The article also includes weather maps for longer-term U.S. outlooks and a six-day World weather outlook which can be very useful for travelers.

…Scattered showers and thunderstorms push into the central/southern
Appalachians and Southeast today…

…Wet snow and wintry mix over the central High Plains on Saturday as
heavy rain threat develops over parts of Texas and the lower Mississippi
Valley…

…Unseasonably warm across much of the South and Southwest as below
average temperatures expand throughout the Great Plains and Midwest…

The main weather feature and focus for showers and thunderstorms through
this weekend will be a cold front progressing across the East and stalling
between the Southeast and southern Texas. Unsettled weather will start the
short range forecasting period located across the central/southern
Appalachians and Southeast. These locations will have the greatest chances
for isolated thunderstorms to become strong enough to produce locally
damaging wind gusts and hail. Elsewhere, light showers are expected to
extend into the Northeast through tonight.

Precipitation is also expected to become more widespread and increase in
intensity throughout the central High Plains and Colorado Front Range by
tonight. A mix of rain and snow is likely, with heavy snow (greater than 4
inches) most likely along the Front Range and lesser amounts into the
foothills on eastward into the High Plains. Snow chances should gradually
subside by Saturday evening, but chilly temperatures will remain across
much of the Great Plains on Sunday.

Meanwhile, instances of heavy rain and scattered flash flooding are
possible on Saturday across parts of the southern Plains and lower
Mississippi Valley as numerous showers and embedded thunderstorms develop
to the north of a stationary front. Repeating rounds of intense rainfall
and areas with wet antecedent ground conditions have prompted a Slight
Risk (level 2/4) of Excessive Rainfall between central Texas and the
ArkLaMiss region. Fortunately, this system is forecast to quickly exit to
the east on Sunday and shift shower and thunderstorm chances to the
Southeast, limiting the flooding threat somewhat.

A quick-moving system will also swing light precipiation into the
Northwest this weekend, which will continue to promote above average
temperatures over the Southwest. Spring warmth will also be found
throughout much of the South today and Saturday for places avoiding
afternoon rain. For a majority of the Nation; however, well below average
temperatures will remain locked in place this weekend underneath high
pressure streaming in from Canada. Highs are anticipated to range from the
40s in the northern Plains and Upper Midwest to the 60s from the
Mid-Atlantic to the Tennessee Valley. Lows into the 30s could produce
frost and/or freeze conditions in the Midwest as well.

…Severe weather and isolated flash flooding for the Great Lakes/Ohio
Valley this evening; threat shifts to the Ohio and middle Mississippi
valleys and Southern Plains Thursday…

…Warm to hot temperatures across the southern U.S.; chillier weather
spreading southeast from the northern Rockies/Plains…

Showers and thunderstorms will continue to develop into the evening along
and ahead of a cold front now advancing eastward across Lower Michigan and
the Ohio Valley. Some of these storms may become strong to severe,
producing damaging winds, large hail, and a few tornadoes. In addition to
severe weather, locally heavy rainfall and isolated flash flooding are
concerns as well.

Later this evening, storms are forecast to develop from the central Plains
into the lower Missouri Valley. These storms too may become strong to
severe, with damaging hail expected to be the primary threat.

As the system in Plains moves further east, storms are likely to redevelop
from the Ohio Valley into the southern Plains on Thursday. Severe weather
will once again become a concern, especially across portions of the mid
Mississippi into the lower Ohio valleys. The Storm Prediction Center has
issued an Enhanced Risk (level 3/5) for portions of the region, noting
that strong to severe storms capable of damaging winds, and possibly a few
tornadoes, are likely tomorrow. While widespread heavy rains are not
expected, locally heavy accumulations resulting in isolated flash flooding
are possible.

Temperatures across the southern U.S. will remain warm through the period,
with highs in the upper 80s and 90s common from the Southwest to the
Southeast over the next couple of days. Much cooler temperatures now
centered over the northern Rockies and Plains will spread southeastward,
lowering temperatures across much of the Midwest and Ohio Valley by Friday.

…Storm system to bring the threat of severe weather and isolated flash
flooding to the Mississippi Valley Tuesday and the Lower Great Lakes/Ohio
Valley on Wednesday…

…Moderate to locally heavy snowfall expected over the next couple of
days for the northern Rockies…

…Warm temperatures continue across the South and Desert Southwest,
chillier weather expected for the Upper Great Lakes and northern Rockies…

A seasonably strong low pressure/frontal system over the central U.S. will
move from the Plains into the Mississippi Valley during the day Tuesday. A
sustained arc of showers and thunderstorms wrapping around the low over
the Northern Plains into the Upper Midwest this morning will continue to
progress to the northeast, with more scattered storms extending southward
through the central/southern Plains along an eastward advancing cold
front. A renewed round of storms is expected along and ahead of the cold
front Tuesday afternoon. Strong deep-layer and low-level shear along with
more than sufficient buoyancy will be available in the warm sector for
robust supercell development. The Storm Prediction Center has issued an
Enhanced Risk of Severe Weather (level 3/5) for portions of southern Iowa,
northeastern Missouri, and far western Illinois where these storms will
pose a threat for very large hail, damaging winds, and tornadoes,
including the risk for a strong tornado. A broader Slight Risk (level 2/5)
extends southward through Missouri into northern Arkansas where a more
isolated threat for storms will exist, but will still pose the threat for
all hazards. In addition to severe weather, rounds of heavy rainfall from
the more widespread storms over the Upper Midwest along with potentially
more scattered but heavier downpours with storms to the south through the
Middle Mississippi Valley will pose a threat for some isolated flash
flooding.

The system will continue eastward on Wednesday into the Great Lakes region
and Ohio Valley. Similar to Tuesday, storms will likely be ongoing
overnight Tuesday into early Wednesday, especially to the north from the
Upper Midwest into the Great Lakes. Some scattered storms may also
continue along the cold front as it pushes into the Ohio Valley. A renewed
round of storm development is expected ahead of the front by Wednesday
afternoon, with a Slight Risk of severe weather in place from eastern
Indiana into southern Michigan and western Ohio for the threat of large
hail, damaging winds, and a few tornadoes. The storms are forecast to
continue overnight Wednesday into the Mid-Atlantic. Again, similar to
Tuesday, more widespread rainfall over the Great Lakes and the potential
for some more potent downpours with storms further south will pose a
threat for some isolated flash flooding.

To the West, another upper-level trough/associated surface frontal system
pushing southeastward through the northern Rockies will bring the chance
for some moderate to locally heavy snow for higher elevations in the
mountains of Montana Tuesday and into Wyoming by Wednesday morning. Winter
weather-related advisories and warnings are in place for snow
accumulations generally between 6-12″, with higher amounts more likely in
Wyoming. Some lighter snow showers will also be possible along the
trailing end of the frontal system over the northern Cascades Tuesday.
Otherwise, the remainder of the country will be mostly dry. Temperatures
will tend to generally be at or above average along the southern tier of
the country with cooler temperatures along the northern tier. Forecast
highs in the 80s are expected from the Southern Plains east through the
Southeast, with 70s and 80s for California and the Central Plains east
through the Ohio Valley, and 70s in the Mid-Atlantic. The warmest
temperatures will be over the Desert Southwest as highs climb into the
90s. To the north, 50s and 60s are expected for the Pacific Northwest,
Northern Plains, and New England. Areas of the Upper Great Lakes and
northern Rockies will see the coolest temperatures, with highs mainly in
the 40s by Wednesday.
