Pro / 01
Plan weeks and months ahead
Start with the regional signal and the date you care about, while keeping long-range limits in view.
9-Month Outlook
Scan nine months of regional temperature and precipitation guidance, then open any cell for model agreement, confidence and explanation.
Date Outlook
Choose a place and date up to nine months out for normals and regional guidance, with daily detail inside 44 days.
4-Week Outlook
See the climate signals shaping the next few weeks and what they could mean for your region.
Indices
Follow El Niño, La Niña, AO, NAO, MJO and other drivers through observed history, available projections and typical weather effects.
2-Week Outlook
Read the watch list, compare model disagreements in placement or amounts and see how recent outlooks performed.
Monthly outlook maps
Explore experimental regional pattern, snow, freezing-rain and sleet indices. They are not probabilities, event counts or snowfall forecasts.
CFSv2 seasonal snowfall
View supported monthly and three-month snowfall water-equivalent totals and departures. This is liquid content, not forecast snow depth; missing references remain unavailable.
Pro / 02
Follow weather at your place
Keep the forecast, event list, model spread and alerts tied to locations you follow.
Your forecast
Save locations for daily and hourly forecasts, nearby alerts and radar, with model tools ready for a closer look.
Storm Watch
Group modeled rain and snow into events at a saved location for the next 16 days, with timing, ranges and plume evidence. This is not a WDS forecast.
Storm Timing
See the possible start window for rain, snow or strong wind in local time, then compare model timelines and open a row for times, amounts or gusts. Model counts are not probabilities.
Meteograms
Read hourly temperature, dewpoint, precipitation, wind and gusts at a point, then compare the WDS blend with raw models.
Plumes
Compare ensemble members and recent-run sets at a US point to see whether an eye-catching result has support.
Storm Tracks
Follow developing lows through the GEFS and Euro ensembles and the four most recent runs of GFS, GFS AI, Euro, Euro AI and HRRR, with agreement, spread and central pressure. Paths show model support, not a probability or impacts.
Location alerts
Keep weather alerts tied to saved locations, then open the forecast or radar for detail.
My watches
From inside Storm Watch, follow a regional model signal or set a personal threshold at a saved place. A saved watch does not imply notification delivery.
Pro / 03
Compare model guidance
Hold the valid time and point steady while you inspect runs, fields and the atmosphere above the map.
Model Explorer
Choose a model, field and run, then switch guidance without losing the valid time.
Compare Models
View two compatible models at the same forecast hour, then click a point for its hourly forecast.
Compare Cycles
Wipe between earlier and newer runs at the same valid time to spot changes in the storm track.
Point values and key cities
Show cities and read values, units and forecast times on supported model maps. Unsupported maps clearly mark point values unavailable.
Maps Explorer
Browse forecast and analysis maps outside the model catalog with each source and valid time visible.
Soundings
Open a Skew-T, hodograph, severe ingredients and plain-language read. Supported WDS-rendered GFS and HRRR maps keep your point pinned across forecast hours.
GIF export
Export a loaded Model Explorer loop as a GIF labeled with its model and timing for saving or sharing.
Explorer Favorites
Save personal Model Explorer and Maps selections to reopen in later signed-in sessions.
Pro / 04
Track storms on radar
Move from observed radar into short-range guidance, severe context, storm structure and tropical tracks.
Radar
Replay observed radar with lightning and warnings, then continue into HRRR forecast frames on the same timeline.
Radar Scenes
Open built-in everyday, severe, winter, tropical or analytical layers, or save a personal scene that follows your account across devices.
SIX threat context
WDS threat cones use multi-hazard SIX levels beside official watches and warnings, never as their replacement.
3D radar on the web
Draw around a storm to inspect its height, core, lean or a vertical slice. Web 3D requires supported graphics; native 3D is not included.
Analog Storm Tracks
Compare a current cyclone with similar historical paths. The NHC or CPHC track remains the official forecast.
Tropical Forecast Path
View experimental WDS tropical guidance beside official products, with its source, timing and confidence limits visible.
Ensemble storm tracks
Follow GEFS, ECMWF ENS and AIFS ENS member tracks and experimental consensus. These are model runs; NHC or CPHC remains official.
Pro / 05
Observe, learn and share
Use your station history and signed-in guides to understand what you are seeing.
My Station
Connect a compatible station for current readings, history, records and storm recaps.
Microclimate profile
After about 14 quality-checked days, compare your station’s lows, highs and rainfall with a chosen official reference.
Signed-in Help
Search guides approved for your current workspace and tools, including interpretation, availability and troubleshooting.
Optional forecaster memberships
Add your
favorite forecaster.
Follow the people whose forecasts you look forward to. Get their forecasts for your location, understand their thinking and join the conversation for $5/month on top of Pro, one forecaster at a time.

A few useful details.
Are forecaster memberships included in Pro?
No. Pro includes every tool listed here for $14.95/month after its seven-day free trial. A forecaster membership adds their forecasts and community for another $5/month. Pro plus a forecaster is $19.95/month after the seven-day free trial.
I saw 4070 in a video. Do I need that forecaster’s membership?
No. You can use the Pro tools you saw, explore your own locations and follow the weather yourself. A forecaster membership is only needed for that forecaster’s subscriber forecasts and community.
How does adding a forecaster work?
Choose a forecaster when you start Pro and both are free for seven days, then $19.95/month (or $219.45/year). Already a member? Add a forecaster in Settings. On a monthly membership nothing is charged that day: the rest of the month and then $5 a month are added to your Pro bill. On a yearly membership the rest of your year is charged that day, then $55 a year.
Can I have more than one forecaster?
One at a time. To switch, remove your forecaster in Settings, then choose the other one.
Can I follow a forecaster for my location?
Choose a forecaster who covers your area to get their published forecasts and join their community. Coverage and publications vary by forecaster; your Pro tools remain available independently.
How do I get access?
Start your seven-day free trial from the signup page: choose your plan and your first location. Existing members keep using the member sign-in.
Start your free trialCan I ask the 4070 Assistant about the forecast?
4070 Assistant weather Q&A is part of the planned Pro experience. Chat, forecaster communities and forecast publications depend on your membership.
Is the nine-month outlook a forecast for my exact address?
It shows regional monthly temperature and precipitation guidance. Meteograms, plumes and your saved-location forecast give you the local view at shorter ranges.
Does Pro include dedicated meteorologist support?
Dedicated support belongs to WDS business services. Pro includes the tools; forecaster memberships add their forecasts, briefings and communities.
