A new weather system began bringing isolated rain and snowfall to North India's higher elevations on Monday, February 9. This system will also lead to a gradual increase in temperatures across the plains, including Delhi, over the coming days. The India Meteorological Department (IMD) reported a fresh Western Disturbance moving into the region.^[1][2] ### Himalayan Region to See Snow and Rain The Western Disturbance, characterized as a trough in the upper atmosphere, started impacting the Western Himalayan region on Monday, February 9.^[1][2] This system is expected to cause isolated to scattered rainfall or snowfall across Jammu and Kashmir, Ladakh, Gilgit, Baltistan, and Muzaffarabad.^[1] The wet spell will extend to Himachal Pradesh and Uttarakhand between February 9 and February 11.^[1] By Tuesday, February 10, the weather in the higher reaches could become more intense. The IMD predicts thunderstorms, lightning, and gusty winds, potentially reaching speeds of 30 to 40 kilometers per hour.^[1][2] This activity brings a much-needed dusting of snow to the high altitudes.^[1] ### Delhi's Warming Trend Continues Delhi experienced a slightly warmer start to its Monday, February 9, with shallow fog noted in parts of the city during early hours.^[3] The minimum temperature recorded was around 9 degrees Celsius, signaling a slow transition out of the colder winter conditions.^[3] This warming trend is set to continue. Minimum temperatures across Northwest India are projected to climb gradually by about two degrees Celsius over the next two days, before stabilizing.^[1][2] For Delhi and the National Capital Region, maximum temperatures are expected to hover steadily between 23 and 26 degrees Celsius.^[1] From February 10 to February 14, daytime temperatures in Delhi are forecast to range between 23 and 25 degrees Celsius.^[3] Nighttime minimums will likely stay cool, ranging from 10 to 12 degrees Celsius during this period.^[3] Historically, February in Delhi often sees temperatures rising from an average of 24 degrees Celsius at the start of the month to 29.4 degrees Celsius by the end.^[4] While precipitation is generally rare in Delhi during February, with fewer than two rainy days on average, some forecasts indicate a slight chance of rain, around 5% to 10%, particularly around February 12 and 13.^[5][4] The city typically enjoys around 11 hours of sunlight daily in February, with comfortable conditions due to low humidity.^[6] ### Fog and Air Quality Concerns Persist Despite the warmer temperatures, shallow fog and mist are expected to continue during early mornings and late nights in Delhi over the coming days.^[3] Commuters in the northern plains may still face hazy conditions. Dense to very dense fog is also forecast to persist during morning and night hours in isolated pockets of Uttar Pradesh and Uttarakhand until Tuesday, February 10.^[1] Visibility has already dropped to zero meters in areas like Bareilly and Gorakhpur, making driving hazardous.^[1] Fog may also affect northern Tamil Nadu, Bihar, and parts of Northeast India through Monday, February 9.^[1] Beyond the fog, air quality remains a concern for Delhi. The city's Air Quality Index (AQI) continues to fall into the "poor" category, with readings surpassing the 200 mark.^[3] Humidity levels in Delhi are expected to remain moderate, between 50 and 60 percent, during this period of rising temperatures.^[3] Clear skies and bright sunshine are predicted during the day, maintaining overall normal weather conditions across Delhi and the NCR.^[3] The gradual shift towards milder weather signifies the slow exit of the deep winter chill from the region. While the mountains welcome fresh snow, the plains will experience a steady warming trend.
