🌡️ About Lewis Weather
Your hyperlocal source for live weather in Cowesett (also known as Cowessett), Warwick, Rhode Island — ZIP 02886.
About the Lewis Weather Station
Lewis Weather is a free, community weather service operated by the Lewis family in the Cowesett neighborhood of Warwick, Rhode Island (ZIP code 02886). We've been providing live local weather data to Warwick-area residents since 1996 — long before commercial weather apps offered meaningful hyperlocal accuracy.
Cowesett (sometimes spelled Cowessett — the original Narragansett name for the area) sits in the western part of Warwick, bounded by Apponaug, Greenwood, and the Kent County border. Its position relative to Narragansett Bay and local topography creates a distinct microclimate that differs meaningfully from the conditions measured at T.F. Green Airport (PVD) — the source most weather apps use for "Warwick" readings.
Our station fills that gap. The Tempest sensor at 41.6885°N, 71.4562°W measures conditions at ground level in central Cowesett, updated every minute. Whether you're gardening, planning a backyard event, or watching a storm roll in off the bay, Lewis Weather gives you the most accurate Warwick, RI weather data available from a private station.
Weather Station Hardware
Lewis Weather is powered by the Tempest WeatherFlow all-in-one weather sensor (Station #46690, Device #136082). The Tempest is an award-winning personal weather station that combines six instruments into a single maintenance-free unit:
📡 Sensors Onboard
Ultrasonic anemometer — measures wind speed and direction with no moving parts, providing accurate readings even in light breezes where cup anemometers stall. Haptic rain sensor — detects individual raindrops by vibration, enabling rain to be reported in near real-time rather than waiting for accumulation in a tipping bucket. Temperature & humidity sensors with active radiation shielding from the solar panel. Barometric pressure updated multiple times per minute. UV index & solar radiation for sun exposure and energy tracking. Lightning detector using AS3935 Franklin lightning sensor — counts strikes and estimates distance in real time.
🔬 AI-Powered Calibration
WeatherFlow uses machine learning to cross-reference every Tempest reading against a network of nearby stations and NWS observations, applying continuous calibration corrections. This "Better Forecast" engine is what makes the Tempest's 10-day forecast particularly accurate for hyperlocal locations like Cowesett.

About Cowesett, Warwick, Rhode Island
Cowesett (also historically spelled Cowessett) is a neighborhood within the city of Warwick, Rhode Island — the second-largest city in the state, located in Kent County just south of Providence. The name derives from the Narragansett language and was the name of a Native American settlement in the area prior to English colonization.
Warwick ZIP code 02886 covers much of the Cowesett area, including residential neighborhoods west of Route 2 and north of Route 117. The area is bordered by the Pawtuxet River watershed to the north and the Apponaug Cove inlet of Narragansett Bay to the east — geographic features that influence local weather patterns, particularly sea breezes, fog formation, and storm intensification.
Rhode Island's coastal weather can change rapidly. Having a live sensor in Cowesett means residents get accurate precipitation timing and totals rather than relying on readings from T.F. Green (2.4 miles away) or Providence (10+ miles), where microclimatic differences often result in meaningfully different rainfall, wind, and temperature readings.
