As per reports, adverse weather conditions are expected in parts of the US through Monday (27 January).

• A deep upper low and associated frontal system are moving southward across the western US, bringing snowfall from the Great Basin to the Rockies and central High Plains. Low pressure over the Southwest through Monday (27 January) is expected to increase winds and rainfall. While strong winds and dry conditions may elevate wildfire risks in parts of Arizona, rainfall will ease fire weather conditions in southern California, where moderate to heavy rainfall may cause debris flows and flash flooding near burn scars.
• Low pressure along the US-Canada border is driving frontal systems across the Central US The leading front is bringing limited rainfall to the southern Plains and Great Lakes, while a second front is triggering snowfall in the northern Plains and Upper Midwest. By Sunday (26 January), precipitation chances will extend into the Gulf Coast, Lower Mississippi Valley, and Southeast, with heavy rainfall potentially causing flash flooding along the Texas Gulf Coast and Lower Mississippi Valley.
• Snowfall will spread into the northern and central Appalachians and interior of New England, with locally heavy snowfall possibly in northern New York, particularly downwind of Lake Ontario. The southern portion of the front will stall near the Gulf Coast, while the northern portion moves across the Northeast and Mid-Atlantic.
• Temperatures along the Gulf and East Coasts will begin a warming trend, rising from five to 15 degrees below average on Saturday (25 January) to near-average by Sunday (26 January) and Monday (27 January). Cooler conditions will persist in the Central US following a cold front, with temperatures 15-25 degrees below average in the Rockies and High Plains. Meanwhile, a warm front will bring above-average temperatures to the north-central US by Monday (27 January), and below-average temperatures will dominate the Southwest due to the upper low.
